摘要
报道了一种声光调Q激光二极管抽运Nd:YVO4晶体腔外五倍频213 nm深紫外全固态激光器。实验上分别利用KTP和两块BBO晶体产生532 nm倍频绿光,266 nm紫外四倍频以及基波与四倍频的混频,实现了从Nd:YVO4近红外激光到213 nm深紫外激光的频率变换。在10.3 W抽运功率下,获得平均输出功率3.1 mW,脉宽7.5 ns的213 nm深紫外激光输出。
Abstract
A compact and efficient 213 nm deep-ultraviolet all solid state laser based on Q-switched laser diode (LD)-pumped Nd:YVO4 laser is presented. In the experiment, KTP crystal (KTiOPO4) and BBO crystal (beta-BaB2O4) are used for the 532 nm second-harmonic generation and the 266 nm fourth-harmonic generation respectively. Subsequent sum-frequency mixing is performed in a second BBO crystal to mix the fourth-harmonic at 266 nm and the residual fundamental at 1064 nm. At 10.3 W of incident pump power, the average power of 3.1 mW at 213 nm with the pulse width of 7.5 ns is obtained.
