We demonstrated a high-power single-frequency, single-polarization, thulium-doped all-fiber MOPA system. The linearly-polarized thulium-doped fiber MOPA yielded 192 W of single-frequency output at central wavelength of 2001 nm with a polarization extinction ratio of >15 dB.
We report on a high-energy ultrafast thulium-doped all-fiber master oscillator power amplifier system with a pulse energy of 85 nJ and a pulsewidth of 8 ps. The seed laser was passively mode-locked by a semiconductor-saturable absorber mirror to generate average power 16 mW at a pulse repetition rate of 14.7 MHz in a linear cavity. A one-stage single-mode thulium-doped fiber amplifier was used directly...
