单频钕玻璃激光器最佳耦合Q开关理论的实验研究

Experimental Research of Theory of the Optimally Coupled Q-Switched Single-Frequency Nd:glass laser

本文描述一个单频改玻璃激光器。采用腔反射镜选模技术,并根据最佳耦合Q开关理论,腔镜的每个表面镀以12％的增反膜,获得了脉宽60us、能量3.5mJ的单模激光器脉冲输出。其实验结果与最佳耦合Q开关激光理论的预测值一致。

A Single frequency Nd:glass laser with resonant reflectors as longitudinal mo-de selector is described. From the consideration of theory of the optimallycoupled Q--switched laser, the reflectivity of each face of the resonant refleetorsis coated to be 12%. Stable output pulses of 60ns width, up to 3.5mJ energy areobtained. The experimental results are in good agreement with the prediction ofthe theory of the optimally coupled Q switched laser.
