Paper Abstract

We demonstrate on chirped pulse amplification of a dissipative soliton thulium-doped fiber laser. The system consists of an all-fiber seed laser, a fiber-based stretcher, two-stage fiber amplifier and a free space grating compressor. The oscillator works in the normal dispersion regime and delivers up-chirped pulses with output power of 3 mW at repetition rate of 29.3 MHz. The spectrum of the seed laser is located at 1938 nm with a 10 dB bandwidth of 50 nm. The output pulses are directly stretched in ~50 m normal dispersion fiber to 72 ps pulse duration. In the pre-amplifier and power amplifier, both forward pumping and backward pumping are tested in the experiment. Output power of 7 W has been achieved in the power amplifier with backward pumping corresponding to a pulse energy of 239 nJ, which has an amplification slope efficiency of 37.8%. The PER at the highest average output power was measured to be 19.5 dB. The amplified up-chirped pulses could be dechirped to a duration time of 121 fs with energy of 161 nJ using a pair of fused silica transmission gratings.
