Analysis of China 's Laser Industry
In fact, blue laser pointer processing equipment in addition to the ever-increasing demand for power, has been committed to the quality of equipment assurance and technology development. The cost-effective ratio of laser processing equipment refers to the continuous reduction of product prices relative to performance guarantees, so that customers really use "cheap" products, rather than to sacrifice product performance, reduce equipment configuration to reduce the price, nor is it simple The pursuit of processing efficiency at the expense of processing stability. Laser processing equipment stability and efficiency is a contradiction, the product in the industry and the application market has been widely recognized, the formation of the brand, because the equipment has been cutting the stability of the first place, and the stability of the main indicators are Equipment failure rate.
In recent years, domestic and international laser industry mergers and acquisitions frequently, because the laser industry low level of repeated investment seriously lead to overcapacity and industrial transformation and upgrading of the demand coexist. Before 2010, high-power green laser pointer equipment industry also belongs to high-profit high-return industry. However, due to investment and technical threshold is not high, a lot of money into the market quickly showed a vicious competition situation. However, many companies have overlooked that the industry in fact the process threshold is high. Do not attach importance to process development, in the homogeneous competition environment, in order to pursue a lower price advantage, reduce equipment configuration and thus reduce the performance of equipment becomes inevitable, which led directly to a group of enterprises died, a number of enterprises overcapacity. While the excess capacity to make the advantages of mergers and acquisitions to reduce the cost of mergers and acquisitions began to prevail this stage. On the other hand, with the transformation and upgrading of the Chinese market continues to deepen, as the transformation and upgrading tool industry, the laser industry into a period of rapid development.
Power laser welding machine, host, power supply, table, refrigeration unit split design; the machine into my company's new condenser cavity, the photoelectric conversion efficiency, excellent beam quality, reflective surface and cooling medium without contact, cavity Long life, easy to replace xenon lamp and no need to adjust the optical path. PLC control and computer control in two ways to choose, the machine output power is stable, reliable performance, compact structure, beautiful appearance, easy to operate, with coaxial, paraxial gas protection device to improve the welding quality; and optional high power laser cutting Head, for cutting to expand the processing range.
Since the second quarter of this year, the market demand for equipment, the rapid increase in power, and soon from 4KW, 6KW to 8KW. Has been the customer's demand to upgrade to more than million watts, mainly due to customer processing capacity of laser processing equipment and processing efficiency requirements. On the one hand is the original customer with the same material with the thickness of the material cutting efficiency requirements, on the other hand is constantly emerging new areas of laser technology processing needs, especially for ultra-thick processing of materials processing requirements to laser processing technology Alternative to other processing technology.
China's manufacturing industry and intelligent manufacturing is still very far away from the industry 2.0 to industrial 4.0, China still has a long way to go. Germany's industrial 4.0 has hard power, the US industrial 4.0 has soft power, while China's industrial 4.0, 2.0, 3.0 and 4.0 are simultaneously developed. On the red laser pointer industry, whether it is the market demand or industry requirements, from the equipment automation requirements are still distance, and intelligent requirements, whether technical or market base are far worse. However, in new areas of new markets, the demand for automation equipment has increased significantly, especially in key industries and high-end customers.

Laser Technology Challenges Thin and Brittle Nonmetallic Materials
Laser as an advanced processing tool, has more and more widely in the industrial production plays a pivotal role. With the continuous development of green laser pointer technology, its by virtue of the processing quality, processing complexity, processing efficiency and clean environmental protection and other advantages, not only in the stainless steel, copper, alloy and other metal materials processing favored, but also in the glass , Ceramics, sapphire, semiconductor silicon wafers, PCB board and other non-metallic materials processing highlights the unique advantages.
In these applications, glass, sapphire or ceramic and other materials, the thickness is usually thin, the hardness is getting higher and higher, very fragile. In the processing requirements, the application usually requires the use of these fine brittle materials on the very precise cutting, drilling and even slotting and other processing, which makes the traditional milling, drilling, grinding and other mechanical processing technology is facing Great challenge, because the material is extremely thin and very brittle, any stress applied to the material during contact with the process, may lead to material fragmentation, the final scrapped. However, the challenges faced by traditional machining methods have brought more opportunities for non-contact laser pen processing.
Glass, ceramics, sapphire and other brittle non-metallic materials, precision machining, usually using ultra-fast laser. Ultrafast laser pulse duration is extremely short, in nanoseconds, picoseconds and even femtosecond, the role of moderate laser energy on the surface of the material, by breaking the material chemical bond to achieve the purpose of material removal, in this process, the laser energy It is too late to pass around the processing range, the process has ended, so the heat is almost negligible, the material does not produce thermal damage. With the application of these brittle materials in products such as LEDs, smart phones, wearable equipment, etc., blue laser pointer, Laser technology in the field of brittle materials continue to break through.
The unique performance of glass, sapphire and other brittle, transparent materials will enable it to gain ever-increasing use in consumer electronics, medical equipment, integrated circuits, construction, automotive, aerospace and other market segments. Especially in the smart phone, wearing equipment, led by consumer electronics products, the strengthening of glass and sapphire applications, will have a lot of room for growth. Therefore, the market for brittle materials, laser processing needs are very good.
While the market is demanding high demand from the market to reduce processing steps, reduce material waste and dry process and other factors continue to drive, is also a strong impetus to the laser manufacturers and laser system integrators to provide continuous discussion, asking them not only to provide Traditional mechanical processing alternatives, but also continue to enhance the overall performance of laser pointer processing solutions to the processing quality, product yield, processing speed and mass production has been a breakthrough.

The key factor of high energy laser weapon
High energy laser weapons mainly rely on the following three kinds of effects to carry out the destruction the target:When burning laser beam irradiate the target, the huge energy transformed into heat energy. At the same time, the part of the droplets and solid particles, so that the target surface perforation and destructionCompared with the fire weapon, the laser weapon has the following six characteristics:Laser beam reach the targets at the speed of light. At present, all military targets, including altitude satellite, relative to the speed of light is a stationary target, so when shooting don't need advance.
Laser weapon VS nuclear weapon
Volley multi-objective, emitting a 100mw Laser Pointer beam without recoil, easy to quickly transform the direction of fire and shooting high frequency, can volley incoming targets in a short period of time.Laser weapons are non nuclear weapons, unlike nuclear weapons, in addition to shock, heat radiation and other serious damage, but also the existence of long-term radioactive contamination, resulting in large-scale pollution areas.Although laser weapon production costs are high, but due to long-term use, and each launch cost is very low, still has quite high cost-effectiveness.Laser transmission is not interfered by external electromagnetic interference, so it is difficult to use electromagnetic interference to avoid the attack of laser weapons.
In order to deal with the threat of antiship missile,defense system must find the target as soon as possible, increasing detection distance of the sensor to target so that there is sufficient response time for system; Using multiple layers of defense system to develop the world's most powerful laser pointer weapon systems and improve the precision of damage.
The main characteristics of foreign weapon systems.
A. reaction time is short. Due to the low altitude radar distance is short, the response time of the foreign weapon systems general is about 6S, for ultra high speed flying target, tracking and shooting directly so as to shorten the reaction time.
B. with all-weather working ability. Some weapon system can even use the infrared thermal imaging technology.
C. anti jamming performance is good.
American high energy laser weapon system
The United States Navy set up a naval high energy laser (HEL) Program Management Office (PMS-405) in 1971 , intended build a high energy 200mw Laser Pointer weapon system . The initial plan focused on the construction of an experimental high energy laser system based on the then most mature CO2 aerodynamic laser technology. But by the mid 1970s, focus on the development of chemical laser. The navy has awarded TRW a contract to design and build a chemical laser (NACL) for the Navy's advanced research projects agency, which is an order of magnitude higher than its predecessor's laboratory prototype. At the same time, the target / tracker (NPT), which is made by the Hughes Co, is used as a light beam control device. NACL/NPT combination is much better than any previous laser weapon system, and provides valuable engineering experience for the integration of laser and beam control devices.This achievement is the most credible evidence of the possible level of high energy laser weapons at that time, and laid the foundation for entering the "sea stone" (Sealite) program.
Current situation of the development of solid state laser and ultra fast laser
History of laser technique
The development of the burning laser technique has been more than 60 years, its application covers almost all the industrial areas, except for light industrial, automotive, aerospace, power and energy industry, it is gradually come to the fine and micro manufacturing fields expand, a strong impetus to the electronics manufacturing, integrated circuit, communication, machinery micro processing, medical, dental, beauty equipment and new application development.
Even in the global economic downturn, the laser market is still a good performance, including solid state lasers, ultrafast lasers, laser technology in precision machining, micro machining field showing sustained growth. Especially in China, although 2015 GDP growth dropped to 6.9%, hit the lowest growth rate since 1990, the laser industry there is still good growth.
According to the research report, the global 5000mw Laser market will grow from $10 billion 90 million in 2015 to $14 billion 670 million in 2022, an average annual compound growth rate of 5.33%.China industrial laser market sales revenue of about $530 million, accounting for 19.2% of the world, but the market growth rate is relatively fast, in 2015 an increase of 18.9%.
Cold working technology to promote the development of solid state lasers and ultrafast lasers
Compared with the optical fiber and CO2 200mw Green Laser , the advantage of the narrow pulse width of the solid laser is outstanding, and can achieve the fine micro machining that other laser can not achieve ". These lasers have large output energy, high peak power, compact structure, durable, price appropriate; the number of types of processing; there are a variety of wavelength selectable, narrow pulse width, etc.. Especially with the appearance of a large number of high performance materials, the performance of the solid state lasers has been greatly improved, so that the solid state lasers will be expanded to more emerging applications.
2015, the global sales revenue of the solid Red Laser Pointer market sales of about $470 million, China is about $100 million. The global manufacturing sector has more than half the market in Asia, most of them in China, but also make China one of the most important market for solid laser. Ener laser, spectra physics such as a group of the strength of the enterprises to promote solid laser in the application of China made a significant contribution. And the global consumer electronics market unpopular, especially smartphones to accelerate the replacement, such as fingerprint module, sapphire cover new application has covered many models, the fine micro processing put forward more requirements, will greatly promote sales of solid state laser.
Threats from Chinese laser weapon!
Localization of high power fiber laser in China
Recently, China's first implementation of the "high power fiber Green Laser Pointer " core component of the national production targets, marking China has possessed the "million kilowatt class" solid-state laser weapon system light source independent R & D and production capacity, and laid a solid foundation for independent control of high power solid state laser equipment.
It is understood that the realization of the core components of the national production is a high power pump coupler. This device is one of the key components in the fiber laser. The so-called "pump" coupler and its main function is a plurality of thin fiber energy convergence to a root crude fiber of higher output power energy, its working principle is like the roots of the trees as: many lateral roots to soil moisture transport and convergence to after their taproot were injected into the tree trunk, taproot and lateral root water absorption, water capacity is stronger, trees can get more water to flourish.
At present, the domestic "high power fiber burning laser end pumped coupler are almost imported products monopoly, not only the existence of the embargo, for the risk of breaking and import product price high, long period of procurement, specifications varieties are limited, technical performance index is also difficult to meet the requirements of weapon equipment development. In order to get rid of the dependence on imports of core device, scientific research departments of China proposed "high power fiber laser in the core device of the full realization of the localization of target, under the efforts of all the researchers finally realized this goal.
Public data shows, high power laser from hundreds of watts to tens of thousands of Watts range, they like very sharp, the all conquering sword, both to qualified for the automotive, marine, aviation and other fields of laser cutting, laser welding and laser drilling, Daxian in high energy laser weapon skill, for high-end manufacturing building blocks, escort for the cause of national defense.
Localization of the core elements of laser weapons is very important for China
Military experts of the wire military "said laser weapon is a directed energy weapons, using directional emission of powerful Red Laser Pointer beam directly damage or failure. It is a high technology and new concept weapon that uses the huge energy of high brightness and high power laser beam to destroy or kill the enemy aircraft, missiles, satellites and personnel. Laser weapons have advantages unparalleled in other weapons, high energy laser weapon has speed, high precision, intercept distance, transfer of fire quickly, without outside interference of electromagnetic wave, continuous fighting capacity and other advantages.
Because of this, the United States, Russia, Britain, Germany, France, Israel and many other western countries are actively developing strong 30000mw Laser weapons. China is no exception, and the level of the best. Earlier, the media has exposed a low altitude, slow, small target of low security equipment. That is the first set of Chinese kW class low slow small target laser interception system -- "low guard" system. In the real scene demonstration, "low altitude" Guardian successfully shot down fixed wing, small multi rotor, helicopters and other aircraft more than 30 sorties, shot down rate of 100%. After more than thirty years of research, the laser weapon has become more and more mature and will play a more and more important role in the future. So the localization of the core elements of the laser weapon is very important for China.
A creative gift for your travel crazy friends!
This Laser Pointer is amazing. What can’t it do? I wanted a laser point and with this item received so much more.This has a very bright green laser pointer light that is easy to see when the lights are off and also it can be easily seen when the lights are on. At home I play with my cats with it, they love chasing the green dot.
This burning laser is really very bright, sharp and visible out to long distances. It is true that there is no power adjustment, so if this is really important to you because you want to use it indoors at night for example, considering how bright it is, you may want to consider a different product, although you still might be happy with it even for that use, as I am. We'll see over time how well it holds up, but considering how well built it feels and how well it performs, I'm guessing this is a product that is made to last. I couldn't be happier with my purchase, or should I say purchases because I just ordered two more!
Awesome laser you can see it 100yds out in the shade, sunlight of course eliminates the green dot. The 200mw Laser is made completely out of metal and feels very well built. This has two different mounts for rail mount or scope mount, and two different switches. The first switch is a push button constant on, the second is a remote pressure switch that can be mounted by the trigger; this will turn the laser on as long as you keep it pressed.Quality all metal construction, battery included, green laser so intense you can see it for 300+ yards at night, and I have it on my Ruger SR9 and it fits and looks perfect. Not bad for China made.
I used a green laser to 'move' several hundred mallards from a marina. Red lasers didn't work. Unless you have experienced this, you have no idea how disturbing it can be to have scores of buzzards decide to roost in your trees. They chew plastic/rubber molding on cars...and asphalt roofing...for some mysterious reason.Works great, fits very snug and doesn't wobble or lose zero. Even when I moved it from a Glock, to a Ruger sr9, it held zero. Very bright too.
So I tried this Red Laser on my air pistol (see pictures). What I like about it is that it's bright, it has very good range, the build quality is good, it has exceptional adjustment with good precision, and the attachment is versatile. So the key here is the accuracy of the laser and it's adjustment precision. The alan wrench adjustment is the key for the precision so this and the fact that the laser is bright is the real selling point. Therefore I recommend this product.
