报道了一种基于电光-可饱和吸收主被动双调Q技术的窄脉冲宽度、高峰值功率946nm全固态激光器.该激光器采用808nm脉冲半导体激光侧面泵浦长尺寸Nd∶YAG晶体棒抽运方式和双凹型折叠谐振腔结构,并将横向加压式的双45°角切割掺氧化镁铌酸锂晶体电光调Q与单层二硒化钼被动可饱和吸收调Q相结合,通过优化设计谐振腔结构,在脉冲重复频率550 Hz时,获得了最大单脉冲能量3.15mJ、脉冲宽度9.1ns、峰值功率高达346kW的946nm主被动双调Q脉冲激光的稳定输出,脉冲宽度和能量的峰峰值不稳定度分别达到±2.87%和±3.42%,光束质量因子分别为M_x~2=3.851和M_y~2=3.870. 

Other Abstract

An active-passive double Q-switched 946 nm laser was reported which with a double 45° cut-magnesium oxide doped LiNbO3 electro-optic crystal and a monolayer molybdenum selenide saturable absorber. In order to obtain 946 nm laser pulses with high energy and high peak power, a pulsed laser diode side-pumped long Nd: YAG rod is used as the gain medium in a folded biconcave cavity. Output pulses with maximum pulse energy and peak power up to 3.15 mJ and 346 kW were obtained, corresponding to 550 Hz repetition rate and 9.1 ns pulse duration at 946 nm. Peak to peak instabilities of pulse width and pulse energy were ±2.87% and ±3.42%, beam quality factors were Mx2=3.851 and My2=3.870. © 2018, Science Press. All right reserved.
