An existing sodium lidar, installed at Colorado State University, makes significant geophysical measurements of temperature profiles in the mesopause region. An important element of this transmitter is a stable, narrowband cw laser beam that seeds the high power pulsed dye amplifier. The present unit, consisting of an argon-ion laser and single-mode ring dye laser, has the versatility required of an exploratory system, but has excessive space, power and maintenance requirements. Thus, a compact, solid-state cw light source is being developed at the Desert Research Institute. The PI will modify this solid state light source into an operational, portable unit by (1) mounting it on a small optical breadboard with enclosure, making the mechanical and optical setup more rugged; (2) developing simple and fast tuning and locking procedure to stabilize the output wavelength to Doppler free features of the sodium spectrum; and (3) testing and using the system in conjunction with the existing sodium lidar at CSU.

现有的钠激光雷达，安装在科罗拉多州立大学，使显着的地球物理测量的温度分布在中层顶区域。 这种发射机的一个重要组成部分是一个稳定的，窄带连续激光束种子的高功率脉冲染料放大器。 本装置由氩离子激光器和单模环形染料激光器组成，具有探测系统所需的多功能性，但具有过多的空间、功率和维护要求。 因此，沙漠研究所正在开发一种紧凑的固态连续波光源。 PI将通过以下方式将该固态光源改造为可操作的便携式装置：（1）将其安装在带外壳的小型光学试验板上，使机械和光学设置更加坚固;（2）开发简单快速的调谐和锁定程序，以稳定输出波长，使其符合钠光谱的无多普勒特征;以及（3）结合CSU现有的钠激光雷达测试和使用该系统。
