“…High energy pulsed fiber lasers are playing more and more important roles in many applications, such as laser sensing, laser imagery coherent Lidar, free space optical communications, and material processing due to their many advantages such as compact, light-weight, reliable operation, and high wall-plug efficiency [1][2][3][4][5][6][7][8]. In eye safe wind-profiling Lidar applications, stable single-frequency oscillation, good pulse shape, a relatively long pulse width, linear polarized output are required at low repetition rate down to Hz level.…”
