摘要
利用半导体激光器(LD)连续单端泵浦Nd:YVO4晶体,实现了声光调Q输出1064nm的短脉冲。分析并用实验验证了不同透过率输出耦合镜及不同重复频率条件下,输出调Q脉冲能量、脉冲宽度及平均输出功率的规律。在泵浦功率为20.7W,重复频率为50kHz时,获得了最大平均输出功率为5.72W的脉冲,光 光转换效率为28%,斜效率为32.4%;在重复频率为10kHz时,最大单脉冲能量为0.286mJ,脉宽为22ns,峰值功率为13kW。
A high power LD pumped acousto-optic Q-switched Nd:YVO_4 laser is reported. Short pulse of 1 064nmis obtained. Output energy, pulse width and average output power are measured with different conditions such as different output coupling mirrors and repetition rates. When repetition pulse is 50kHz, the maximum average output power of 5.72W is obtained with an optical conversion efficiency of 28% and a slope efficiency of 32.4%.As repetition is 10kHz and pulse width is 22ns, the maximum single pulse energy of 0.286mJ and peak power of 13kW are acquired.
