摘要
报道了调谐范围达130 nm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32.8 mW。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783~913 nm连续可调谐输出,在840 nm处获得115 mW的最大输出功率,在800~900 nm的区间内,输出功率超过80 mW。用棱镜作为调谐元件,调谐范围达802~887 nm,最大输出功率为6.5 mW。从调谐范围和输出功率看,BF的调谐效果更好。
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 32.8 mW 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 6.5 mW. 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.
