摘要

在激光破坏机理研究中,经常关注材料对入射激光的反射率随辐照面温度的变化规律。利用基于积分球法的反射率测量系统,测量了915 nm激光辐照下45#钢对3.8 μm探针光的反射率的变化,确定了探针光辐照区的温度变化。结果表明,反射率的快速减小是由高温下样品表面快速氧化导致的,反射率随温度的缓慢变化是由电导率随温度变化导致的。

Abstract

In the study of laser damage mechanism, the change rule of incident laser reflectivity by materials versus the irradiated surface temperature is always concerned. Under the irradiation of a 915 nm laser, the change of the 3.8 μm probe laser reflectivity by 915 nm laser irradiated 45# steels is measured by the reflectivity measurement system based on the integrating sphere method. The temperature change of the irradiated regions is determined. The results show that the steep decrease of reflectivity is caused by the rapid oxidation of specimen surfaces at high temperature, and the slow variation of reflectivity with temperature is the result of the variation of conductivity with the temperature change.
