A laser diode (LD)-pumped high polarization state intracavity frequency doubling all-solid green laser is reported. By using two optical axis orthogonal Nd∶YVO4 crystals to act as laser gain medium, eliminating the depolarization effect of single Nd∶YVO4 crystal, the high polarization green laser is obtained. And with optical contact between each crystal, the micro-chip green laser is realized. With the injection pump power of 1.8 W, 336 mW TEM00 green laser at 532 nm is achieved, the light-light conversion efficiency is up to 18.7%, and the polarization rate is 110∶1. This laser has the advantages of being simple and easily attainable at a low cost, and it is suitable for batch production.
