Abstract

We report on an all-fiber single-mode master oscillator power amplifier system delivering high peak power picosecond solitons at 1960 nm. The Bragg stabilized oscillator delivers 4.5 ps transform-limited pulses at 11.2 MHz. The pulse energy is equal to 62 pJ. Solitons are amplified up to 32 nJ in a short highly Thuliumdoped single-mode fiber amplifier pumped into the core at 1560 nm. The average output power achives 360 mW and the pulse peak power reaches 9.1 kW with little self-phase-modulation distortion. The amplified pulse duration is about 3.5 ps and the slope efficiency is equal to 13 %.
