Multi-GHz repetition rate femtosecond electro-optic frequency comb based on one single phase modulator and non-linear processes

Abstract

We report on a multi-GHz repetition rate, femtosecond fiber laser operating in the burst mode, achieved by nonlinearly shaping and amplifying a phase-only modulated electro-optic comb at 1.03 μm. The system delivers an average power of 1.2 W with pulses compressible down to sub 100 fs.
