大多数天基观测系统进行与水汽和温度相关的测量，而用于风测量的天基观测系统有限。目前的被动天基风观测系统具有覆盖面积大、时间和水平分辨率高、垂直分辨率低的特点。世界气象组织（WMO）希望开发天基风廓线系统。多普勒风激光雷达（DWL）是一种有用的、强大的风测量技术，它可以设计成紧凑的移动、机载和天基系统。DWL将为我们提供垂直分辨率高、偏差小、精度好的风廓线，是填补当前观测空白的必要条件。国家信息和通信技术研究所（NICT）正在为未来天基相干DWL开发单频高能Tm，Ho:YLF激光器，2 μm关键技术和仪器。我们演示了Tm，Ho:YLF激光器，其脉冲能量为125 mJ，工作频率为30 Hz，满足未来天基相干DWL的要求。在本文中，我们将描述NICT的最新进展。
Most of space-based observing systems make water-vapor- and temperature-related measurements, while spacebased observing systems for wind measurement is limited. The current passive space-based observing systems for wind measurement has a large coverage area and high temporal and horizontal resolutions but has a low vertical resolution. The World Meteorological Organization (WMO) wants to develop space-based wind profiling systems. A Doppler Wind Lidar (DWL) is a useful and power technology for wind measurement and it can be designed as compact mobile, airborne, and space-based systems. DWL would provide us with a wind profile having high vertical resolution, low bias, and good precision, and it is necessary to fill the gap of current observations. The National Institute of Information and Communications Technology (NICT) is developing a single-frequency high-energy Tm,Ho:YLF laser, 2-μm key technology and instrument for a future space-based coherent DWL. We demonstrated the Tm,Ho:YLF laser producing a pulse energy of 125 mJ operating at 30 Hz meeting requirements for the future spacebased coherent DWL. In the paper, we will describe recent progress at NICT.
