摘　　要：针对热键合直角棱镜和角锥棱镜构成的946 nm激光器,详细讨论了输出端946 nm介质膜反射镜对单频运转的影响及热稳定性问题。指出通过改变p分量的透射比不能有效增加腔内激光的线偏振度;增强施加在角锥棱镜上的磁场强度,不仅可以显著提高腔内激光的线偏振度,减小输出激光的损耗,而且可在提供相同环路损耗差的情况下,降低对946 nm激光p分量的高透要求。通过传播矩阵方法,研究了该准单块非平面环形腔的热稳定性及高斯光束能量分布问题。Influence of 946 nm dielectric output mirror on single-frequency operation and thermal stability are discussed in detail for the 946 nm laser consisting of thermally bonded Porro prism and corner cube. Degree of linear polarization inside the cavity will not increase significantly by changing the transmittance of p component, while enhancement of the magnetic field applied to the corner cube will not only raise degree of linear polarization inside the cavity efficiently and reduce the output loss, but also decrease the transmittance of p component for the same roundtrip loss difference. Thermal stability and Gaussian beam distribution of this quasi-monolithic non-planar ring cavity are studied by method of propagation matrix.
