Why fiber laser cutting machine has high photoelectric conversion rate?
Experts know that the photoelectric conversion rate of fiber laser cutting machine is 25%-30%. And the photoelectric conversion rate of YAG laser cutting machine is 2%-3%. And the photoelectric conversion rate of CO2 laser cutting machine is 10%. So it is not difficult to see that the photoelectric conversion rate of optical fiber laser cutting machine is the highest. Why fiber laser cutting machine has so high photoelectric conversion rate?
XT LASER believes that there are two main reasons.
1. Different laser generators.
Fiber laser can output high energy density laser beam. And gather on the surface of the workpiece. So that the area of the workpiece illuminat the ultra focus spot instantly melting and gasification. If the fiber laser cutting machine add to the numerical control system. At will be able to realize automatic cutting.
2. Laser output mode is different.
However CO2 laser cutting machine drive laser power laser tube to emit light. It refract through a plurality of reflectors. Light transmission to the laser head. A focusing mirror on the laser head light converging point. This point temperature is very high, can be sublimated into material instant gas. By the exhaust fan suction came to cutting objective. But fiber laser cutting machine is different, it is the optical fiber to transmit the laser. The beam is relatively concentrated, small loss, high photoelectric conversion rate.
