双频固体激光器产生相干脉冲输出的研究进展

光载波雷达（LidarRadar）是一种新型体制的激光雷达，它采用激光拍频产生的射频信号作为探测媒介，在保证激光探测的高空间分辨力优点的同时相对于普通激光雷达具有更强的抗大气干扰能力，其中作为探测光源的二极管抽运的双频固体激光器是其关键技术之一。针对光载波雷达的具体应用要求对光学脉冲相干的双频固体激光器进行了分析，并报道了最新研究成果。

Progress on pulse-to-pulse coherent beat note generated by two-frequency solid-state lasers

Lidar-radar is a new system hybrid laser radar using laser beam carrying radio-frequency beat note to execute the distance and velocity detection applications,which has more anti-jamming ability but maintain high spatial resolution.The research status and prospect of lidar-radar system are reviewed.As one of the key technologies,the pulsed two frequency solid-state laser are analyzed and discussed.Some of the preliminary study results are presented.
