摘要

High-power single-frequency lasers have been found widespread applications in science and industries,such as gravitational wave detection,coherent and spectrum beam combining,range finding,and lidar[1- 7].In such cases,the localization of high-power single-frequency fiber laser is extremely important for domestic researchers.The power of single-frequency fiber lasers has increased dramatically in recent years.Most previously presented high-power single-frequency fiber lasers are based on bulk optics configuration,which have big sizes and massive weights.The use of aIl-fiber-based components can significantly simplify the system configuration and make the system more compact and robust[8-10].In this letter,we report a high-power single-frequency master oscillator power amplifier (MOPA) fiber laser in all-fiber format.The MOPA fiber laser consists of twostage amplification architecture.The maximum output power is 122 W,with slope efficiency of 72％.
