N2 - In this article, we discuss the designs and performances of narrow-linewidth erbium-ytterbium fiber MOPA for coherent detection lidars. We report on pedestal and multifilament core erbium-ytterbium large mode area fibers specially designed to generate high energy and good beam quality. Pulse energy of 220 μJ with M2 < 1.4 are obtained with all-fiber three amplification stages. An additional amplifier stage generates 600 μJ with M2 < 2.4. We present the first results of pulsed fiber lidar wake vortices detection using a coherent detection lidar. Maturation of this technology leads to compact all-fiber lasers. Several commercial laser sources for lidars are finally described.
