Long range coherent detection wind lidars have many applications in the fields of wind farms and aircraft  safety. Fiber laser sources emitting around 1.5 µm show key advantages such as versatility, modularity and obustness of alignments to vibrations. However, nonlinear effects such as Stimulated-Brillouin-Scattering limit achievable peak power because of strong fiber core confinement.
