摘　　要：给出了一种适用于空间应用的全固态高重复频率窄脉冲激光器。激光器采用超稳双porro棱镜直线谐振腔,以LD侧面抽运Nd…YAG板条,磷酸氧钛铷(RTP)晶体作为电光调Q开关,并利用偏振耦合输出激光。实现了激光脉冲重复频率为1kHz、平均功率为1.15W、脉冲宽度为1.3ns、光束质量因子M^2为M_x^2=1.20和M_y^2=1.23、波长为1064nm的脉冲激光输出。激光器结构紧凑,性能良好,可作为未来新型空间探测激光雷达系统的光源。A all solid-state laser with high repetition frequency and narrow pulse width for space applications is shown. The laser adopts ultra-stable double porro prism cavity, using laser diode side pumping, the rubidium titanyl phosphate （RTP） crystal as electro-optically Q-switched switch, and polarization-coupled outputting. The system achieves 1 kHz laser pulse repetition frequency, 1. 15 W average power, 1.3 ns pulse width, the beam quality factor M2 of two directions of Mx2 = 1.20, My2 = 1.23, the output wavelength of 1064 nm. The laser has a compact structure and good performance, which can be used as the light source for the new space detection lidar in the future.
