Abstract
Coherent wind LIDARs are increasingly used for climatic condition and turbulence assessment with applications in wind farm projects optimization or aircraft security during take-off and landing. Laser pulses are sent through the atmosphere and wind speed is measured using Doppler-induced frequency shift on the backscattered laser light. Laser sources with excellent spatial beam quality, narrow linewidth and typical pulse duration ranging from ~100 ns to 1 μs are required. Pulsed master oscillator power fiber amplifier (MOPFA) at 1.5 μm are well adapted, versatile sources but with peak power limited to a few 100s W by nonlinear effects in standard fibers.
