Study of a Diode-Pumped Actively Q-Switched Nd:YAG Ceramic 1319 nm Laser
摘要
报道了激光二极管端面抽运声光调Q陶瓷Nd:YAG在 1319 nm波长处的调Q运转。在抽运功率23.7 W时,平均输出功率为4.8 W,重复频率为30 kHz,脉冲宽度为110 ns,对应的光-光转换效率为20.3%。在抽运功率为19.4 W时,得到了脉宽78.5 ns、能量为316 μJ、重复频率为10 kHz的稳定调Q脉冲。
Abstract
An efficient diode-pumped actively Q-switched Nd:YAG ceramic laser operating at 1319 nm was demonstrated. At an incident pump power of 23.7 W, average output power of 4.8 W at pulse repetition frequency of 30 kHz and pulse duration of 110 ns was obtained. The corresponding optical-to-optical conversion efficiency is 20.3%. A maximum single pulse energy of 316 μJ with a pulse duration of 78.5 ns is obtained at incident pump power of 19.4 W at pulse repetition frequency of 10 kHz.
