摘要

为了获得高功率、高重复频率的紫外脉冲激光器, 采用1064nm基频光通过三硼酸锂(LBO)晶体与3次谐波355nm进行和频得到4次谐波266nm紫外激光的方法, 进行了实验验证, 取得了重复频率为20kHz、紫外激光器的平均输出功率为2.5W、红外到紫外的转换效率为12.5%的实验数据。结果表明, 此脉冲激光器利用LBO晶体在高重复频率下取得了较大的紫外平均输出功率。

Abstract

In order to achieve the ultraviolet pulsed laser with the high power and high frequency, the fourth harmonic 266nm in LiB3O5 (LBO)crystal was generated by frequency mixing of the fundamental(1064nm) and third harmonic (355nm) of electro-optical Q-switched laser, and experiment verification was carried out. Deep ultraviolet (UV) output power of 2.5W at 266nm with the repetition rate at 20kHz and 12.5% infrared(IR)-to-UV conversion efficiency were achieved. The result show that the pulse laser has achieved a large average output power at high repetition frequency by using LBO crystal.
