0.7W all-fiber Erbium oscillator generating 64 fs wave breaking-free pulses.
We report on the generation of wave breaking-free pulses from a passively mode-locked all-fiber Erbium oscillator at 1.55 microm pumped by a Raman fiber assembly operating at 1.48 microm. The extracted pulses show a self-similar behaviour and can be scaled up to an average power of 675 mW only limited by the pump power. The laser operates at the fundamental repetition rate of 108 MHz, therefore the pulse energy is 6.2 nJ. After external compression, the dechirped pulse duration is 64 fs.
