Spectrally resolved optical frequency comb from a self-referenced 5 GHz femtosecond laser

Albrecht Bartels, Raphael Gebs, Matt Kirchner +1

We report a mode-locked Ti:sapphire femtosecond laser with 5GHz repetition rate. Spectral broadening of the 24 fs pulses in a microstructured fiber yields an octave-spanning spectr…
