A unique 946 nm and 473 nm 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 2 mm thick Nd∶YAG crystal,the Porro prism supplies multi-functions such as laser amplification,closuring the light path,polarization sensitivity to the 946 nm and so on.By applying the ring permanent magnet,the corner cube made of fuse silica is used to supply Faraday rotation effect.473 nm single-frequency and unidirectional blue laser by intracavity-frequency-doubling is achieved in the experiment.
