一种基于Cr4+:YAG晶体的紧凑高效被动调Q脉冲激光器
A Compact and Highly Efficient Passively Q-Switched Pulsed Laser Based on Cr4+:YAG Crystal
摘要
Abstract
A compact and highly efficient all solid-state 1 064 nm laser has been researched and designed based on a Nd:YVO4crystal. While operating in continuous wave state,a maximum laser output of 2.49 W is obtained with the input pump power of 7.8 W,which corresponds to an optical-optical conversion efficiency of 31.92% and a slope efficiency of 35.77%. Based on it,a small piece of Cr4+:YAG crystal with the dimession of 3 mm×3 mm×1 mm is inserted into the cavity as the passive Q-switched device,and then stable 1 064 nm pulse operations are observed. By optimizing the resonator cavity length to 9 cm,the average power of 2.13 W Q-switched pulse trains are obtained with the pump power of 7.8 W,and the corresponding optical-optical conversion efficiency,the repetition rate,and the pulse width are 27.31%,357.1 kHz,and 75 ns,respectively.关键词
