LD-pumped Actively Electro-optic Q-switching Lasers With Pulse Repetition Rates up to 5 kHz

本文描述了连续二极管激光器(LD)端面泵浦Nd:YVO4晶体,在200-5000 Hz电光调Q的情况下,激光输出特性的研究。当二极管输入电流在25 A(约10 W),电光Q开关重复率为1 kHz时,1064 nm激光的平均输出功率为160 mW,脉宽为20 ns。并对实验结果进行了分析和讨论。

The characteristic of a continuous-wave (CW) laser diode (LD) end-pumped Nd:YVO crstal electro-optic Q-swtiching with pulse repetition rate from 20 to 5000 Hz laser is presented in this paper. With 25 A (about 10 W) of the incident pump laser, 1 kHz of pulse repetition rates, Q-switching 1064 nm laser with average power of 160 mW, pulse width of 20 ns is obtained. The experimental results are analyzed and discussed.
