title: Coherent multi-frequency optical source generation using a femto-second laser and its application for coherent population trapping.
abstract: We present a coherent multi-frequency source generated from a mode-locked femto-second laser. The key concept for the coherent multi-frequency source generation is using the mode-locked femto-second laser as many continuous wave (CW) optical sources. We simultaneously selected and amplified the desired modes of the optical frequency comb using femto-second laser injection-locking (FSLIL). Using two coherent sources generated by the mode-locked femto-second laser, we have demonstrated a coherent spectroscopy in a Lambda-type system of the Cs D2 line. The proposed coherent multi-frequency source generation technique will be a useful technique for optical frequency standards based on multi-photon schemes.
