高功率CO_2激光束发散角的测量

Measurements of beam divergences in high power CO_2 lasers

理论和实验研究了高功率CO_2激光器的光束发散角测量。对三种不同测量方法进行了理论分析,给出了相应公式和计算曲线。

The characteristics of measurements of beam divergence in high power CO2 lasers were studied theoretically and experimentally. The theoretical analyses of three measure-ment meaasea were made, and the corresponding formulas and theoretical calculation curved were given. The theory coincides well with the experimental results.
