In this paper, we propose a 1.5 μm all-fiber lidar system for atmospheric wind field measurements. The lidar emission source adopts the master oscillator power amplifier 1532 nm single-frequency all-fiber structure with a repetition frequency of 10 kHz. The lidar output energy is 427 μJ, and the maximum peak power is 610 W at the pulse width of 700 ns. The system utilizes Doppler wind speed coherent measurement technology, and the lidar source modulates an 80 MHz intermediate frequency carrier. The maximum longitudinal height signal distance of the lidar system is 4.5 km for atmospheric wind field, and the measurement accuracy can be within the range of 10-2 level. The lidar system can be used to detect high-altitude or long-distance high-precision wind field information. At the same time, the system can play an important role in future atmospheric environment engineering research. Keywords: fiber laser, lidar, coherent Doppler measurement, wind field, vertical measurement. DOI: 10.61011/TPL.2023.08.56686.19536
