摘　　要：为实现激光二极管(LD)抽运腔内和频491 nm蓝光激光器,从准三能级和四能级阈值和频理论出发,讨论和分析了1063 nm和912 nm激光双波长运转的条件。在实验中,采用标称输出功率为3 W的LD,端面抽运尺寸为3 mm×3 mm×2 mm,掺杂原子数分数为0.15%的Nd:GdVO4晶体,利用线性直腔结构在腔内实现912 nm和1063 nm双波长同时振荡,并利用LBO晶体进行Ⅰ类腔内和频,获得了连续0.8 mW 491 nm蓝色激光输出。In order to obtain LD-pumped intracavity sum-frequency 491 nm blue laser, the oscillation conditions for the simultaneous dual-wavelength operation of 1063 nm and 912 nm were analyzed based on the threshold expressions of quasi-three-level and four-level system. In the experiment, a Nd ： GdVO4 laser crystal with doped concentration of 0.15% （atomic fraction） and size of 3 mm× 3 mm× 2 mm was pumped by a laser diode with the maximum output power of 3 W. A linear cavity setup was used to realize 912 nm and 1063 nm dual-wavelength operation. 0.8 mW 491 nm blue laser is obtained after a LBO crystal was inserted into the cavity as the sum frequency crystal.
