研制了一台2 μ m波长的相干多普勒激光雷达，其输出能量比现有的激光雷达高（100 mJ）。激光发射器基于二极管泵浦Ho：Tm：LuLiF，这是一种最近开发的激光材料，可以更有效地提取能量。单频操作是通过斜坡和火灾注入播种技术。采用先进的光电探测器架构，将光电二极管纳入双平衡配置。建立了一个数字信号处理系统，可以实时显示风和气溶胶后向散射数据产品。高脉冲能量和接收器效率提供了测量风场的范围以前没有见过的2 μ m激光雷达，并举例风测量表明这种能力。(c)2007年，由光学仪器工程师协会（Society of Photo-Optical Instrumentation Engineers）主办。
A coherent Doppler lidar at 2 mu m wavelength has been built with higher output energy (100 mJ) than previously available. The laser transmitter is based on diode-pumped Ho:Tm:LuLiF, a recently developed laser material that allows more efficient energy extraction. Single-frequency operation is achieved by a ramp-and-fire injection seeding technique. An advanced photodetector architecture is used incorporating photodiodes in a dual-balanced configuration. A digital signal processing system has been built, allowing real-time display of wind and aerosol backscatter data products. The high pulse energy and receiver efficiency provides for measurement of wind fields to ranges not seen before with 2 mu m lidars, and example wind measurements were made to show this capability.
