beam divergence angle

基本解释

The output parameters such as beam divergence angle in far-field output power of high power solid state lasers are variable due to thermal effect of optical pumping.
由于光泵浦热效应，高功率固体激光器的输出参数如光束远场发散角、输出功率等会发生变化。
Furthermore, the parameters, such as beam width and divergence angle, are also introduced to describe propagation properties. The theoretical results agree with experimental results well.
采用本文介绍的模型，选取合适的参数，得到此类半导体激光器器件的远场发散角和强度分布，理论结果与实测结果吻合。
This method in the invention is only measuring in the one position of the optical path; therefore the method can facilitate to realize the real-time measurement of the beam divergence angle.
本发明方法只在光路中的一个位置测量即可，因此本发明方法可方便地实现光束发散角的实时测量。
