High resolution atomic coherent control via spectral phase manipulation of an optical frequency comb

Abstract

We demonstrate high resolution coherent control of cold atomic Rubidium utilizing spectral phase manipulation of a femtosecond optical frequency comb. Transient coherent accumulation versus pulse number is directly manifest in the enhancement of the signal amplitude and resolution. The combination of frequency comb technology and spectral phase manipulation enables coherent control techniques to enter a new regime with natural linewidth limited resolutions.
