Kilowatt Level Fiber Laser

As a new light source, laser has the characteristics of good directivity, high brightness, good color and high energy density. Laser based laser industry has developed rapidly in the world, and has been widely used in industrial production, communications, information processing, medical, military, cultural, educational and scientific research. According to statistics, from high-end optical fiber to the common bar code scanners, and laser related products and services market value of up to trillions of dollars each year. The blue laser pointer industry has formed a complete and mature industry chain distribution, upstream mainly includes laser materials and matching components, mainly for middle and supporting all kinds of laser equipment, laser application in the downstream products, consumer products, instruments and equipment. The domestic laser market mainly includes laser processing equipment, optical communication devices and equipment, laser equipment, laser, laser medical equipment, laser components, application lies in industrial processing and optical communication market, both of which occupy nearly 7 of the market share.

But in 2016 the industrial laser in the global manufacturing industry enjoyed another growth year, this is mainly due to the surge in high power fiber lasers up to two digit sales growth, income growth and significant excimer laser ultrafast laser applications. A kilowatt class fiber laser used in metal cutting and welding, accounting for 41% of total industrial laser revenues in 2016. Overall, sales of fiber lasers grew by 12% in 2016, partly due to a fall in sales of CO2 lasers (-4%) and solid-state lasers (- 1%). According to the percentage of high power direct diode burning laser and excimer laser in recent years has won the most rapid annual income growth (54%), the laser has been in a strong growth in the market, because of their low base, the application of excimer laser annealing is a major driving force.

New technology trends, market demand will also drive innovation in laser display enterprises. Up to now, after several years of market precipitation, laser projection products have been in the big screen / large screen, home theater / TV two dominant markets stand firm, the market also showed a trend of heavy growth. At present, the domestic laser projection industry is from the past to simply provide products began to change to provide users with a systematic solution, from high-end products import into domestic brands rising rapidly. In addition to break its own brand line, active cultural market is the impetus of development of laser projection industry, laser projection technology is in the transition from the fluorescent powder of three primary colors, and high added value has become the focus of the development of the brand solutions and value-added products.

Household projection and green laser pointer TV products are receiving increasing attention. Brightness, contrast, color, and cost constitute a “performance paradox” of traditional home projector products”. That is, the use of high contrast and bright environment requires high brightness of products, while the high brightness of mercury lamp often means the decline of color and the increase of cost. So, go out Xiaoheiwu mode is the biggest bottleneck home projector market development. The laser products just overcome this, forming a high brightness, contrast and color of the three high position, and is expected to gradually decline in costs, into the family. At present, Dewey video also has developed to the three primary colors of pure laser as light source of laser TV and home projector prototype. Believe that the popularity of laser TV is not far away.

The more asymmetric the information, the greater the price change. The information asymmetry was one of the main reasons of laser cutting machine industry profits, which is not only the objective limitations of social communication and communication technology, there are subjective reasons for manufacturers circulation artificial limits on the regional market information. With the gradual deepening of market-oriented and information technology, the problem of asymmetric information is being solved, so that the price of laser cutting machines, conventional machines and accessories are basically transparent. And, along with the Internet and other media tools publicity, brand awareness diffusion (non customer recognition) is very simple and easy. Eliminating information asymmetry and expanding popularity can be done from different sales channels of laser cutting machines.

In the red laser cutting machine is more and more mature today, the brand, product and enterprise competition, has not been a single element of competition, in addition to price, quality dominant factors, an important aspect of services, value-added, channel, enterprise development strategy is the recessive elements of enterprise and brand long-term development, sustainable development of competition. Only in the complex market environment to prepare for brutal competition, can stand erect in the world laser cutting machine brand forest.

Back Reflection Protection Technology for Fiber Laser

With the increasing popularity of fiber lasers in metal sheet metal cutting and welding applications, users are increasingly aware of one of the weaknesses of fiber lasers: they are susceptible to damage from backlit reflections from metal parts.

If the 20mw laser pointer retroreflective protection capability is not strong enough, even if the high power QBH or QD transport fiber designed to withstand the kilogram of retroreflective peeling off the fiber cladding, the back-emitting laser beam passes through the fiber core of the transfer line Reflected back into the fiber inside the laser. Even technology-leading fiber laser manufacturers have experienced a variety of painful lessons, system integrators have realized that the laser fiber coupler, or laser module will be damaged.

The new CF series lasers already incorporate advanced back-to-back reflection technology and a well-dispersed, retroreflective laser, stripping off the back-reflecting burning laser pointer beam and providing safe consumption at the critical point of the laser by proprietary pattern stripping Scattered interference light. This sophisticated retro-reflective technology has been tested and its robustness has been proven to be more sensitive to back-reflecting lasers in kilowatt-class fiber amplifiers. The combination of these retroreflective protection schemes in the new CF series fiber lasers verifies its unparalleled performance in cutting and welding a wide variety of highly reflective metal materials with a thickness ranging from <0.5mm to thickness to 25mm.

In contrast to the usual performance of third parties, and depending on the material and settings, the fiber laser has a retroreflective capability of up to 3 to 30 times the resistance due to its special optical configuration. In particular, the CF laser system incorporates these protection schemes that have demonstrated the offset error of the focal position in the millimeter scale that allows large amounts of brass and brass to be tested. Compared to other fiber high power laser pointer manufacturers, it shows a smaller focus position offset error; when operating a CF laser with a unique proprietary protection scheme, the reliability of the laser and the performance of almost no failure have been demonstrated.
