Laser comparison

Whether the disc laser in the laser cutting machine will end fiber laser outshine others situation? Both from the technical level, optical fiber laser and the disc laser photoelectric conversion rate were 30%, About 35%, the output power in 0 w - Between 20 kw; But in terms of beam quality, fiber laser is better than laser discs, but most industrial applications such as car body welding, cutting and application of a good beam quality is not a wise choice. However in the super fast, ultra-short laser pulse field of application of disc has obvious advantages. From the market level: international laser industry giants - — Germany it choose disc laser as the main light source in the high-end industrial application promotion, to achieve single disc 6 kw, 6 mm * mrad beam quality, and integration of disc laser welding equipment has been widely used in automobile manufacturing industry; Interpublic companies in the United States advocate kw to million watts of fiber laser, and the market prospects look good. From the application level: under continuous output 200 w cutting field of laser power, fiber laser has obvious advantages, but in the field of more than 200 w laser cutting, welding, the disc solid laser obvious advantages; On the other hand, a super fast, application of ultrashort pulse laser micro processing areas, disc fiber has obvious advantages. Although from the above three aspects are difficult to determine who actor who bad, but who is more cost-effective, who can better meet the demand of the market, after testing the market. Disc laser due to solve the problem of the traditional solid laser thermal lens effect, even under high power can keep good beam quality. The characteristics of high conversion efficiency, low operating cost to make it play a unique advantage in industrial application. As the laser power output capacity of each disc crystal growing, large disc laser output power will continue to innovation is high, and prices will gradually decline, it will be more and more widely applied in industrial manufacturing
