Paper Abstract

We report a high average power pulsed Tm-doped fiber laser with one stage MOPA (master oscillation power amplifier) structure. The seed source is an AOM (acousto-optic modulation) Q-switched thulium fiber laser with an average power of 2W, the wavelength is 1996.7nm, and the line-width is about 0.1nm. By one stage MOPA, we obtain the maximum average output power of 16W with nanosecond pulse width at 41kHz repetition rate, the central wavelength is 1996.7nm, and the pulse width is less than 200ns, the polarization extinction ratio is better than 20 dB. The optical-tooptical conversion efficiency is 41%, and no nonlinear effect is observed.
