Abstract

A monostatic biaxial Doppler lidar apparatus was made utilizing a hybrid CO2 laser with an intracavity telescopic beam expander. The energy per laser pulse was 10 mJ, the pulse duration was 3–5 μs, and the pulse-repetition frequency was up to 10 Hz. The lidar was intended for measuring the radial component of the wind velocity in the lower troposphere with a probing range of 3–6 km.

用于测量风速的多普勒二氧化碳激光雷达
利用混合式CO2激光器和腔内伸缩光束扩展器,研制了单稳态双轴多普勒激光雷达。激光脉冲能量为10 mJ,脉冲持续时间为3 ~ 5 μs,脉冲重复频率高达10 Hz。该激光雷达用于测量对流层低层风速的径向分量,探测范围为3-6公里。
