摘要
报道了一种基于电光腔倒空技术的高重复频率、短脉冲Nd:YVO4激光器。该激光器以880 nm连续波激光二极管作为端面抽运源,采用BBO晶体组成的普克尔盒作为电光Q开关。通过优化谐振腔,提高了激光器热稳定性和模式匹配效率。在30 W的抽运功率下,获得了脉冲重复频率最高为500 kHz,脉冲宽度为6 ns,平均功率为10 W的1064 nm稳定基横模脉冲激光输出。
Abstract
A high repetition-rate, short-pulse Nd:YVO4 laser based on electro-optical cavity-dumped technology is reported. This laser, end-pumped by a continuous-wave 880 nm laser diode, employs a Pockels cell made up of BBO crystal as the electro-optical Q switch. The laser resonant cavity is optimized to improve its dynamically thermal stability and the mode-matching efficiency. When the pump power is 30 W, stable 1064 nm fundamental-mode laser pulses with the maximum repetition rate of 500 kHz, pulse width of 6 ns and average power of 10 W can be achieved.
