多点抽运单点输出双镜环行激光器

提出并实现了多点抽运、单点输出的双镜非平面环行激光器。该激光器谐振腔由2面反射镜组成，其中1面反射镜直接镀制在激光晶体表面上，所产生的激光在2面腔镜之间沿着非平面光路传播，在谐振腔内形成振荡；该激光器可方便地进行多点端面抽运，降低热效应并提高输出功率；其输出反射镜分成2个扇区，面积大的扇区对振荡激光是全反射的，面积小的扇区对振荡激光是部分透射的，从而实现振荡激光在输出镜上的单点输出，给出了2点抽运时激光单点输出的实验结果。讨论了谐振腔光路模式的特征参数，给出了部分光路模式模拟图。

Diode-pumped at Two Points Two-mirror Ring Laser with Output on Single Point

A multi-end-pumped two-mirrors nonplanar ring laser with output on single point was demonstrated. The beam propagated along a nonplanar loop within the cavity consisting of two mirrors, one of which was coated on the curved surface of the laser crystal. The laser provides the capability in being easily multi-end-pumped to reduce thermal induced effects and scale output power. Two important parameters of beam loops were described, and simulation diagrams of the beam loops were shown. Using the output coupler with the fan-shaped distribution of reflectivity, the output on single point was achieved. Double-endpumped operations of different modes with output on single point were performed and the experimental results were given.
