The laser uses a single-frequency narrow linewidth laser as the seed source and cooperates with a high-power gain fiber module to output single-frequency narrow linewidth laser pulses with high peak value and high energy. The laser wavelength and power are stable, and can be used for coherent lidar, optical fiber sensing systems, etc.
