Research on LD-End-Pumped 457 nm Laser with Straight Type Cavity
摘要
充分利用全固态激光器结构紧凑的优点,设计了一套紧凑型直腔式457 nm蓝光激光器系统。在设计过程中,针对Nd:YVO4激光晶体的自身性质及其产生914 nm激光的相关光学特性,着重对该激光系统的激光阈值进行分析,对温控系统及谐振腔参数进行优化。最终实现了Nd:YVO4激光晶体914 nm波长激光运转,并在此基础上利用BIBO晶体进行腔内倍频获得457 nm激光输出。入射抽运光功率为24.2 W时,最高输出功率为1.56 W,光光转换效率为6.45%,功率稳定度低于2.98%,M2因子为1.3。
Abstract
In order to give full play to the advantages of compact all-solid-state lasers, a compact straight cavity 457 nm blue laser system is designed. Based on the nature of the Nd:YVO4, the analysis of laser threshold of quasi-three-level laser system and the parameters optimization of resonator cavity are obtained. The laser of Nd:YVO4 operation at 914 nm and its 457 nm second harmonic is realized by intracavity frequency doubling with BIBO nonlinear crystal. The highest output power at 457 nm reaches 1.56 W with an incident pump power of 24.2 W, and the optical-to-optical conversion efficiency is higher than 6.45%, also the fluctuation of the blue output power is less than 2.98% and M2 factor is 1.3.
