中文摘要:
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NdYAG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。

英文摘要:
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 1kHz laser pulse repetition frequency,1.15Waverage power,1.3ns pulse width,the beam quality factor M~2 of two directions of M_x~2=1.20,M_y~2=1.23,the output wavelength of 1064nm.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.
