2µm all-fiber dissipative soliton master oscillator power amplifier

We present an all-fiber integrated master oscillator power amplifier operating at 1940 nm. The source delivers 422-nJ chirped pulses at a repetition rate of 10.18 MHz corresponding to 4.3 W of average power. The pulses were recompressed down to 900 fs yielding 220 kW of peak power. Stretching the pulse to 200 ps allows further energy scaling beyond the microjoule barrier at low repetition rate (Ep = 4 μJ at 92 kHz, Δτp =1.6 ps).
