基模稳功率固体激光器的实验研究

Experimental study on solid laser resonator with fundamental mode and stable-power output

本文分析了含有热透镜的固体激光腔,动力学稳定性、模式特性和输出功率特性对动力学因子的依赖关系,得出了稳模输出和稳功率输出的一般条件。实现了连续Nd∶YAG激光器运转在稳功率点,获得较大功率的基模输出。

In this paper, the dependences of dynamic stability, mode property and character of output power on the dynamic factor for a solid laser resonater with a thermal lens is analyzed, and the conditions of stable-mode output and stable-power output under general case are also given. Experimentally the high TEM00 power output of CW Nd : YAG laser operating in the stable-power state is obtained for the first time.
