摘要
报道了一种能获得543 nm激光连续输出的LD抽运全固态激光器, 通过对谐振腔膜系的设计以及倍频晶体的合理选择和放置, 采用长度为10 mm的Ⅰ类临界相位匹配LBO晶体进行腔内倍频, 用功率为2 W的LD抽运掺杂原子数分数为0.8%的Nd:YVO4晶体, 采用简单直腔结构, 获得了543 nm激光输出。在1.9 W的抽运功率下, 最大输出功率为105 mW。光-光转换效率高达5.53%, 输出功率在3 h内长期稳定性优于3%。
Abstract
Continuous wave 543 nm laser emission at powers as high as 105 mW is achieved by using an LD with a power of 2 W to pump 0.8% (atom percent) Nd:YVO4 crystal, with intracavity frequency doubling in a 10 mm long type I critical phase matching LBO crystal and a simple linear resonator. The optical to optical conversion efficiency is up to 5.53% with the incident pump power of 1.9 W, and the long term stability of the output power is better than 3% in 3 h.
