The difference between different lasers of fiber laser cutting machine
Do you know what is the most important thing about fiber laser cutting machine for laser equipment? So what is the difference between CO2 laser and fiber laser? At present, CO2 laser is the mainstream laser processing laser, and then the lamp pumped solid-state laser, followed by the use For medium and small power fiber lasers. The data shows that the sales volume ratio of fiber lasers, lamp-pumped solid-state lasers and DPL lasers in the processing field is 4:3.1:2.9; but the average sales price of high-power CO 2 lasers, lamp pumps, optical fibers, and DPL (diode pumped) They are 150,000 US dollars, 65,000, 20,000, and 22,000. At present, fiber lasers have not achieved the 'obvious advantages of high conversion efficiency and very good beam quality.' According to relevant data, the SPI 200-watt fiber laser used by Guangzhou Industrial Technology Research Institute is not fast enough to cut 1 mm thick steel plates. Millimeters can’t be cut. According to an imported 500-watt lamp pump laser in Chongqing, it can cut 3 mm steel plates at a power of 300-400 watts. According to a 2006 LFW newsletter, a 1000-watt fiber laser can cut 0.5 mm. The steel plate speed greatly exceeds CO2, and it is far inferior to CO2 when cutting 3 mm.
The phenomenon of fiber laser cutting machine just shows the fact and basis that a fiber laser is not accepted by the high-power processing market! Fiber laser has 'very obvious advantages such as flexible processing'? If fiber laser is used for flexible processing , Is the double-clad fiber directly used for transmission, or the light output from the double-clad fiber is re-coupled into the single-mode fiber? So what are the advantages and limitations of fiber lasers? The structure of fiber lasers enables itself to be at high power. With high beam quality, it is also possible to achieve high efficiency! This is its advantage! However, it does not mean that the current IPG and other companies' light lasers have these advantages. The market has already explained that they do not have these advantages.
