摘　　要：报道LD泵浦的全固化单频稳频Nd :YVO4激光器作为泵浦源的外腔谐振倍频绿光激光器。倍频腔采用半整块腔型 ,倍频晶体为MgO :LiNbO3。当倍频腔前的基频光功率为 1W时 ,得到最高绿光输出为 5 0 0mW ,倍频转换效率为 5 0 %。在锁定情况下 ,倍频腔的功率波动小于 2 %。频率稳定性优于 5 0 0KHz。A frequency-doubled laser is pumped by an all-solid freqnency-stabilized Nd:YVO 4 laser, a MgO:LiNbO 3 is used as crystal and using a semi-monolithic external resonator. 500mW green laser is obstained with an input fundamental power of 1W. The SHG efficiency is about 50%, the power fluctuation is less than 2%, and the frequency stability is better than 500KHz. [WT5HZ]
