The output parameters such as beamdivergenceangle 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。

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 beamdivergenceAngle.
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。
