CO2激光器功率分布的实验测量及数值模拟
Measurement and numerical simulation of the power distribution of CO2 laser
摘要
Abstract
In order to obtain the analytic expression for C02 laser power distribution, the power distribution of a C02 laser was measured with thermal paper at the different heights and output power. The experiment images of the laser spot were processed with MATLAB, and a numerical model of laser power distribution was built up and compared with the experimental spot. The obtained analytic expression was verified with the measurement results in laser heat treatment experiments and calculation results of temperature field. The experimental results were in good agreement with the theoretical calculation. The results show that it is feasible to measure the laser power distribution with thermal paper, and it is practical to calculate the power distribution based on the analytic expressions.关键词
