Fiber laser welding machine It's a kind ofLaser welding equipment It is one of the important equipment for the application of laser material processing technology. It can process multiple beams at the same time, which provides conditions for more precise welding. So you know fiber optics Working principle of laser welding machine What is it?
When the pump light passes through the rare earth ions in the optical fiber, it will be absorbed by the rare earth ions. At this time, the electrons of rare earth atoms absorbing photon energy will be excited to a higher lasing level, so as to realize the ion number inversion. The reversed ion number will be transferred from the high-energy level to the ground state in the form of radiation, and release energy to complete the stimulated radiation. Optical fiber Laser welding machine The generated laser is output through the optical fiber and matched with the supporting workbench to complete the corresponding welding. Optical fiber laser welding machine is divided into pulse optical fiber laser welding machine and continuous optical fiber laser welding machine. The pulse fiber laser welding machine can adjust the single point energy of laser pulse by setting the peak power, frequency and pulse width of laser; The continuous fiber laser welding machine adjusts the output laser power by setting the average laser power.
