  • Two stages of stable controlling systems are utilized to inhibit the YAG laser power fluctuation.The frist stage uses back feed of light from laser to control pump supply source so as to make laser self-balanced. The second stage uses electrooptic crystal modulating device further to stabilize laser power. Stable laser radiation power has been obtained with stabilization much better than 0.3% per hour.

Abstract: Two stages of stable controlling systems are utilized to inhibit the YAG laser power fluctuation.The frist stage uses back feed of light from laser to control pump supply source so as to make laser self-balanced. The second stage uses electrooptic crystal modulating device further to stabilize laser power. Stable laser radiation power has been obtained with stabilization much better than 0.3% per hour.
