The end face laser marking machine is called the semiconductor end pumped laser marking machine. The solid-state laser pumped by Laser Diode (LD) is used as the pump source. After laser coupling, the laser crystal is injected from the end face. The pump beam is folded into the gain medium and the cavity mode space to the maximum degree, so that the laser output of high power and high beam quality can be obtained. It adopts integrated integrated structure, no optical pollution, power coupling loss and air cooling. It has high efficiency, long life and less maintenance performance of other lasers.
