LBO Crystal Length on the Efficiency of All Solid-State 473 nm Blue Laser

报道了结构紧凑、输出稳定的473nm连续全固态蓝光激光器。模拟分析了LBO晶体长度与激光输出效率的关系,选择了最佳长度为10mm的Ⅰ类相位匹配的LBO晶体。当抽运功率为3 W时,获得了210 mW的473nm蓝光激光输出功率,光-光转换效率为7%,激光输出功率起伏小于3%。

A compact and stable 473 nm continuous all-solid-state blue laser is reported. Simulation analysis of the relationship between the LBO crystal length and the laser output efficiency is done. An optimal length of 10 mm type I phase-matching LBO crystal is chosen. Under the pump power of 3 W, 210 mW of the blue laser at 473 nm is obtained. The optical-to-optical conversion efficiency is up to 7 %. The fluctuation of laser output power is less than 3%.
