摘要

研制了千赫兹213 nm深紫外全固态激光器。激光器采用脉冲LD侧面泵浦方式和电光调

技术

实现了10瓦级基频光的稳定输出。利用多次倍频技术

实现了稳定的213 nm深紫外激光输出。当LD泵浦电流为80 A时

213 nm激光输出的最大平均功率达到了151 mW

激光器重复频率为1 kHz

激光脉冲宽度为10 ns

功率不稳定度为3%。同时

对激光在非线性晶体中的偏振匹配和不同重复频率条件下的激光器运转特性进行了分析。

Abstract

A kHz 213 nm DUV solid-state-laser was developed adopting LD side-pumping configuration and electro-optical

-switched techniques. A fundamental frequency radiation with the output power of 10 W was presented. The laser system could operate stably at the wavelength of 213 nm using multiple frequency techniques. When the pumping current of LD is 80 A

the maximum average output power of 213 nm beam arrives at 151 mW with the repetition rate of 1 kHz

the pulse width of 10 ns

and the power instability of 3%. Then

the polarization matching of the laser beam in the nonlinear crystal was analyzed. Furthermore

the operation properties of the laser system were studied detailedly under different repetition rates.
