A mode-locked thulium-doped fiber laser based on a nonlinear loop mirror

We have demonstrated an all-fiber mode-locked thulium-doped fiber laser with extremely long pulses, a very narrow spectrum and a high average power. The mode-locker is formed by a nonlinear loop mirror. The laser generates sinus-squared waveform with a repetition period of 82 ns and an average power between 100 and 150 mW. The wavelength is defined by the fiber Bragg grating and is 1956 nm.
