摘要

研究了全固态脉冲运转腔外倍频244 nm深紫外激光器。采用V型谐振腔及主动调Q技术,对双二极管阵列抽运的914 nm和1047 nm基频光进行腔内和频产生488 nm高重复频率脉冲激光。在总抽运功率为44 W时,488 nm激光输出功率为527 mW。利用Ⅰ类相位匹配BBO晶体进行腔外倍频,实现了平均功率为28 mW的244 nm深紫外激光输出,重复频率为4 kHz,脉冲宽度为17.8 ns,倍频效率为5.3%。

Abstract

An all-solid-state ultraviolet 244 nm laser by external cavity double-frequency is designed. Via V-shaped folded-cavity and actively Q-switched technique, the 914 nm and 1047 nm fundamental frequency beams pumped by the double diode arrays are used for intracavity sum frequency generation of a 488 nm high-frequency pulse laser. At the total pumping power of 44 W, the 488 nm laser output power is 527 mW. Using type I phase-matched BBO crystal, the 244 nm deep ultra-violet laser with an average output power of 28 mW is achieved. The repeat rate is 4 kHz with a pulse width of 17.8 ns, and the frequency-doubling conversion efficiency is 5.3%.
