摘要

报道了一台高效率、高峰值功率351 nm紫外激光器。采用激光二极管(LD)端面抽运Nd:YLF晶体声光调Q获得准连续窄脉宽1 053 nm基波振荡, 腔外两块LiB3O5(LBO)晶体紧贴输出镜放置, 对基频光进行二倍频和三倍频, 获得了高峰值功率351 nm紫外激光输出。在LD抽运功率为14 W、声光调 Q 激光器的调制频率为1 kHz的工作条件下, 基波平均输出功率为1.45 W时, 得到351 nm紫外激光平均输出功率450 mW, 1 053 nm基频光到351 nm紫外光转换效率高达31.04%, 脉冲宽度为7.5 ns, 峰值功率达60 kW, 光束质量良好。

Abstract

A Laser Diode(LD) end-pumped Nd:YLF quasi-continuous 351 nm ultraviolet laser with high efficiency and high peak power was demonstrated under acousto-optical Q-switched operation, by using extracavity frequency-doubled and frequency-tripled with two LiB3O5(LBO) crystals cling to the output mirror. An average output power at 351 nm of 450 mW was obtained at repetition rate of 1 kHz, pumped power of 14 W and output power of fundamental wave of 1.45 W. The optical-to-optical conversion efficiency is up to 31.04% and pulse width is 7.5 ns corresponding to the peak power as high as 60 kW.The beam quality is satisfactory.工系统方面的研究。
