2 μm Doppler wind lidar with a Tm:fiber-laser-pumped Ho:YLF laser.

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.
