摘　　要：提出并实现了由热键合直角棱镜与角锥棱镜构成的新型946nm及473nm单频非平面环形激光器.直角棱镜由无掺杂的YAG晶体和2mm厚的Nd∶YAG晶体热键合形成,可提供激光增益、光路闭合及对946nm激光起偏等多种复合功能.角锥棱镜由熔融石英材料构成,在环形永磁铁作用下,提供法拉第旋转作用.实验上实现了该结构的946nm腔内倍频,并获得了473nm单频单向激光输出.A unique 946nm and 473nm single-frequency non-planar ring cavity （NPRC） constituted of a thermally bonded Porro prism and a corner cube is proposed . By thermally bonding the YAG crystal with 2mm thick Nd：YAG crystal, the Porro prism supplies multi-functions such as laser amplification, closuring the light path, polarization sensitivity to the 946nm and so on. By applying the ring permanent magnet, the corner cube made of fuse silica is used to supply Faraday rotation effect. 473nm single-frequency blue laser by intracavity-frequency-doubling is achieved in the experiment.
