Review of Laser Frequency Stabilization Technology in Atmospheric Detection Lidar

Atmospheric detection lidar is widely used in research fields such as atmospheric detection, environmental monitoring, and national defense security due to its high temporal and spatial resolution and high detection accuracy. According to the measurement principle of atmospheric detection lidar, the frequency stability of its light source will have a great influence on the measurement and inversion of atmospheric parameters. Therefore, it is particularly important to stabilize the frequency of the light source. The four laser frequency stabilization technologies and characteristics currently used in atmospheric detection lidar are reviewed. The application research status of these frequency stabilization technologies in atmospheric detection lidar is introduced, which provides reference for the future development of high-precision atmospheric detection lidar.
