Abstract: Power is a basic parameter of the laser.Its' stabilization and accuracy will directly influence laser process and many other fields.The power detection and control system for high power CO2 laser samples the laser power by the transmission light of the high reflective mirror.Furthermore,it can detect and monitor the laser power of the whole system by a S7-200 PLC.It greatly enhances the stabilization and accuracy of the control,and has no influence on the output.
