title: 1 GHz repetition rate femtosecond Yb:fiber laser for direct generation of carrier-envelope offset frequency.
abstract: We report a mode-locked fiber laser working at a 1 GHz fundamental repetition rate. The laser delivers a 600 mW average power at a pump power of 1800 mW. The pulse spectrum bandwidth was 23 nm to support 64 fs near-transform-limited pulses. An octave-spanning supercontinuum from 590 to 1350 nm was generated in a tapered photonic crystal fiber solely with the mode-locked fiber-laser output, without amplifiers. A 30 dB f(ceo) beat signal was detected via f-to-2f interferometer.
