A 2 μm Ho-doped ytrrium lithium fluoride (Ho:YLF) laser end-pumped by a 1.94 μm Tm:fiber laser was developed. A laser system of a ring resonator oscillator and amplifier was operated at repetition rates of 200-5000 Hz at room temperature. The Q-switched outputs were 7.4 W at 5000 Hz and 4.25 W at 200 Hz. Injection seeding was applied to the ring resonator, and single-mode laser emission was obtained. The Tm:fiber-laser-pumped Ho:YLF laser was first used for Doppler wind lidar measurements, and wind profiles were obtained up to ranges of about 15 km in a range resolution of 96 m and an integration time of 1 s.
研制了一种由1.94μm掺铥光纤激光器端面泵浦的2μm掺钬氟化钇锂（Ho:YLF）激光器。一种环形谐振腔振荡器和放大器的激光系统在室温下以200 - 5000Hz的重复频率运行。调Q输出在5000Hz时为7.4W，在200Hz时为4.25W。将注入种子技术应用于环形谐振腔，获得了单模激光发射。掺铥光纤激光器泵浦的Ho:YLF激光器首次用于多普勒测风激光雷达测量，在距离分辨率为96m、积分时间为1s的情况下，获得了高达约15km范围内的风廓线。
