【摘要】 报道了调谐范围达130nm的的V型腔端面泵浦全固化Cr:LiSAF激光器。研究了V型腔结构的重要参数,优化了腔型设计以提高激光器的效率。激光器自由运转输出时,斜效率最高达39.2%,泵浦阈值最低为32.8mW。对比分析了双折射滤光片(BF)和棱镜的调谐效果。在腔内插入BF调谐,实现了783~913nm连续可调谐输出,在840nm处获得115mW的最大输出功率,在800~900nm的区间内,输出功率超过80mW。用棱镜作为调谐元件,调谐范围达802~887nm,最大输出功率为6.5mW。从调谐范围和输出功率看,BF的调谐效果更好。更多还原

【Abstract】 This paper reports an end-pumped all-solid-state continuous wave(CW)Cr:LiSAF laser with a tunability of 130 nm.The design of the V-shaped cavity is carefully studied and optimized to improve the efficiency.The slope efficiency of 39.2%and the threshold of 32.8mW are demonstrated in free running.Tuning range of 783-913 nm and maximum output power of 115 mW are realized when the BF(birefringent filter)is used as the tuning element.However,using the prism for tuning,the tunability decreases to 802-887 nm and the maximum power decreases to 6.5mW.The BF is more suitable for the tuning of the Cr:LiSAF laser compared to the prism.The results indicate that Cr:LiSAF lasers could be widely tunable,high-efficient and compact laser sources in 800 nm region.更多还原
