Abstract
We report on a detailed analysis of frequency noise and intensity dynamics of a free-running femtosecond Ti:sapphire optical frequency comb (OFC) pumped by a multi-mode 532nm laser. We have used these results for phase locking the OFC to a Hz-wide, cavity stabilized, 698nm semicon- ductor laser.An analysis of the in-loop error signals and an estimation of Allan deviation indicates a lowerlimit for the frequency stability of the OFC at the level of 5.3x10^{-14} for 125ms integration time comparable with the clock laser frequency stability over the entire OFC spectrum.File | Dimensione | Formato | |
