摘要
设计并研制了全固态调Q脉冲单纵模Nd:YVO4环形激光器。利用880 nm激光二极管端面抽运Nd:YVO4晶体,通过四镜环形谐振腔中插入声光调Q晶体、标准具,并优化激光谐振腔的结构,获得了重复频率为200 Hz、脉宽为26.6 ns的单纵模脉冲1.064 μm激光输出。当泵浦功率为15 W时,单纵模激光输出的单脉冲能量为570 μJ、脉冲能量稳定性优于3%。
Abstract
An all-solid-state single-longitudinal-mode Q-switch pulse Nd:YVO4ring laser was designed and fabricated.A Nd: YVO4 crystal was directly pumped by an 880 nm laser diode, and a ring cavity formed by 4 mirrors was designed and optimized, an acoustic-optic Q-switch and an etalon was inserted in the cavity, a single-longitudinal-mode pulse laser was achieved with the repetition rate of 200 Hz and the pulse width of 26.6 ns.At pump power of 15 W, the measured pulse energy was 570 μJ with the energy stability of better than3%.
