Fiber transmission laser adopts laser power real-time feedback control system that can combine laser power detection

device based on preset laser waveform to realize real-time closed-loop control of laser power supply and adjust output

current of power supply, thus automatically stabilizing laser energy. Laser power real-time feedback control system can

exclude laser energy instability phenomenon caused by power grid fluctuation, temperature change and xenon lamp aging,

and therefore improve the uniformity of welding products.
