Chinese Abstract

对激光二极管泵浦的Nd: YAG声光调Q腔内倍频固体激光器的折叠腔型进行了研究,当泵浦功率达800W时,在V型腔上实现了脉宽为80 ns、重复频率为10 kHz、发散角为6 mrad、绿光功率为112W的输出;在Z型腔上实现了脉宽为95 ns、重复频率为10kHz、发散角为4mrad、绿光功率为120W的输出。比较两种腔型的实验结果可看出,Z型腔由于插入的光学元件较多,腔长较长,输出激光的脉宽较宽,但输出激光的光束质量有明显的提高。

English Abstract

An LD side-pumped A-O Q-switched intracavity frequency doubled Nd: YAG laser was studied. A folded resonator with a single pump head was experimentally studied and theoretically analyzed. Under the condition of a total pump power of 800 W and a repetition rate of 10 kHz, a beam with a green output power of 112 W, a pulse width of 80 ns and a divergence angle of 6 mrad was achieved when V-shaped resonator was employed. When Z-shaped resonator was employed, a beam with output power of 120 W, pulse width of 95 ns and divergence angle of 4 mrad was obtianed.
