Abstract

This paper introduces a microcomputer claied-loop controller used to control the exciting current of laser power source.The controller is a one chip computer,moded 8031,which is used as a controller and a trigger.The current sampler is a current Hall sensor to provide the exciting current signal.The system is simple and reliable,can widely used in CW Nd:YAG lasers.
