Diagnostic system based on laser brightness amplifier for monitoring and controlling laser technological processes

Abstract

For the diagnostics of processes induced by laser radiation we developed the system on basis of copper laser. This system (laser monitor) consists of laser brightness amplifier, CCD-camera, computer, and allows to obtain the image of a processing surface through plasma plume in a real time. In contradistinction to classical schemes of laser processing our system realizes continuous visual control of processing surface directly in the process of laser radiation interaction with material. The computer analysis of obtained information allows to form control signals for the laser technological complex. The offered system provides the increasing of reliability and accuracy of carrying out measurements and can be used in various technological processes of treatment of metal. In this report we present the result of processing the optical images of dynamic processes on substance surface by fractal geometry methods.
