beam divergence angle

基本解釋

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.
由于光泵浦熱效應，高功率固體激光器的輸出參數(shù)如光束遠場發(fā)散角、輸出功率等會發(fā)生變化。
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.
采用本文介紹的模型，選取合適的參數(shù)，得到此類半導體激光器器件的遠場發(fā)散角和強度分布，理論結(jié)果與實測結(jié)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.
本發(fā)明方法只在光路中的一個位置測量即可，因此本發(fā)明方法可方便地實現(xiàn)光束發(fā)散角的實時測量。
