摘　　要：We demonstrate a diode-pump Tm^（3＋）t-doped all-fiber laser operating at 1908 nm based on a master oscillator power amplifier（MOPA） configuration. In our work, 152 W of laser output power is generated by a total incident pump power of 434 W at 790 nm, corresponding to the total optical efficiency of 35%. The laser wavelength is1908.29 nm. To the best of our knowledge, it is the highest output power reached around 1908 nm with such a narrow linewidth of 0.18 nm based on a MOPA configuration.We demonstrate a diode-pump Tm^（3＋）t-doped all-fiber laser operating at 1908 nm based on a master oscillator power amplifier（MOPA） configuration.
