YAG and fiber laser welding machine works what is the difference between


YAG laser welding machine works
Laser power first put pulse Xenon points with, through laser power on Xenon pulse discharge, formed must frequency, must pulse wide of optical, the optical after concentrated cavity radiation to Nd 3+:YAG laser crystal Shang, inspired Nd 3+:YAG laser crystal glow, again after laser resonance cavity resonance zhihou, issued wavelength for 1064nm Pulse Laser, the Pulse Laser after spread beam, and reflection, and (or by fiber transmission) focused Hou playing in by to welding of objects Shang; in PLC or industrial PC machine of control Xia, Moving CNC, thus completing welding. Pulsed laser welding required frequency, pulse width, waveform, speed of working table are available, mobile SCM, PLC or industrial PC to control, through the laser frequency and adjustable pulse width different set of control pulses of laser energy.
The principle of fibre laser welding machine
When pumping through the optical fiber in the rare earth ion, will be absorbed by rare earth ions. Rare-earth Atom absorbs a photon energy would have incentive to higher emission levels to achieve ion inversion, reverse the ions form of radiation after transfer from a higher level to the ground state, and release energy, completion of stimulated emission. Fiber laser welding machine laser through optical fiber output, and combined with matching table, complete the appropriate welding. Fiber laser welding machine into pulse fiber laser welding machine and CW fiber laser welding machines. Among them, the pulse fiber laser welding machine laser peak power, frequency, pulse width setting to adjust the laser pulse energy; CW fiber laser welding machine by setting the average laser power to adjust the laser output power.
