| contents | Single Longitudinal Mode 2081 nm Thulium Doped Fiber MOPA Laser With Free‐Space Design Wei Liu Youlun Ju Tongyu Dai Jinhe Yuan Chao Liu Qiang Liu Microwave and Optical Technology Letters ABSTRACTA single longitudinal mode thulium doped fiber master‐oscillator‐power‐amplifier (MOPA) laser operating at wavelength of 2081 nm has been developed. The MOPA system employs a free‐space structure with a single longitudinal mode operating Ho:YAG laser serving as the master oscillator, and a Tm‐doped fiber is used for power amplifier. A single longitudinal mode laser with an output power of 7.81 W was extracted from the amplifier by injecting 173 mW of seed laser into the Tm‐doped fiber. The beam quality factor was measured as M2 ~ 1.87. To our knowledge, this is the first study on the amplification of a 2 μm solid state single longitudinal mode laser in Tm‐doped fibers. 10.1002/mop.70270 http://onlinelibrary.wiley.com/termsAndConditions#vor |
