摘要
激光功率是激光器中最基本的参数 ,激光功率的稳定、准确将对激光加工等领域产生直接而巨大的影响。在大功率CO2 激光器功率测控系统中 ,采用尾镜即全反球面镜漏光进行激光功率采样 ,并通过西门子S7 2 0 0PLC实现对整个系统的激光功率测控 ,可以有效提高对激光器的控制精度和稳定性 。
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 CO 2 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.
