A continuous-wave crossed-Porro prism Ho:YAG laser is presented and compared with a corresponding mirror resonator. A maximum output power of 30.7 W is reached with a slope efficiency of 67.4 with respect to the absorbed pump power. The laser output beam shows a very good beam quality of better than M < 1.2 which clearly surpasses that of the mirror resonator. In terms of alignment sensitivity, the crossed-Porro prism resonator is superior to the mirror resonator due to the retro-reflective nature of the prisms in the axis around the apex.
钇铝石榴石激光器，并将其与相应的镜式谐振器进行了比较。相对于吸收的泵浦功率，斜率效率为67.4%时，最大输出功率达到30.7W。激光输出光束显示出非常好的光束质量，M<1.2，明显优于镜式谐振器。在对准灵敏度方面，交叉波罗棱镜谐振器由于棱镜在顶点周围轴向上的后向反射特性，优于镜式谐振器。
