Measurements of the mesopause region temperature using narrowband resonance scattering lidar

我们研制了一种窄带共振散射激光雷达系统，用于测量中顶区温度。该系统由窄带环形染料激光器和Nd: YAG抽运染料激光器组成。我们成功地获得了用于高精度调谐的钠蒸气饱和光谱，并利用注射播种技术研制了高功率窄带脉冲染料激光器。利用该激光系统和现有的激光雷达系统，我们得到了中顶区域的温度分布。

We developed a narrowband resonance scattering lidar system for measurement of the mesopause region temperature. This system consists of a narrowband ring dye laser and a Nd : YAG laser pumped dye laser. We successfully got saturated spectrum of sodium vapor for high accuracy tuning and developed a high power narrowband pulse dye laser using injection seeding technique. Using this laser system and existing lidar system, we got temperature profiles of the mesopause region.
