EXPERIMENTAL RESEARCH ON LASER-MATERIAL INTERACTION

Abstract

This paper presents a new method of real-time measuring technology to investigate the thermo-physical process of laser-material interaction during laser non-melting surface processing. In the thickness direction of the specimen, the temperature distribution was measured with Thermovision Infrared System in real-time. The dynamic micro-deformation of the specimen was studied using laser beam reflex amplifier system. Experiment results display the thermo-physical process of laser-material interaction and lay a foundation of further researching on the process of laser processing.
