摘　　要：采用两支国产2W单芯半导体激光器(DiodeLaser)作泵浦源,双向端面泵浦Nd∶YVO4晶体,由I类临界相位匹配LBO晶体腔内倍频,采用Z型谐振腔结构,在泵浦功率为3.12W的条件下,得到功率为670mW的TEM00模稳定绿光输出,测量表明4h功率稳定性优于3%,偏振比大于500∶1,振幅噪声小于0.5%。A design of dual diodes pumped Nd∶YVO4 crystal,Ityped critical phase matching LBO crystal intracavity frequency doubled green laser at 532nm with Zshaped cavity was described in the paper.Under the condition of 3.12W incident pumping power,green laser output of 670mW with TEM00 mode was obtained at last.Measurements showed the longterm stability in 4 hours better than 3%,polarization rate more than 500∶1,and amplitude fluctuation less than 0.5%.
