Phase dependent interference effects on atomic excitation
arXiv:1101.5839 · doi:10.1016/j.optcom.2011.01.032
Abstract
We present an experimental and theoretical study of phase-dependent interference effects in multi-photon excitation under bichromatic radio-frequency (rf) field. Using an intense rf pulse, we study the interference between the three-photon and one-photon transition between the Zeeman sub-levels of the ground state of Rb that allows us to determine the carrier-envelope phase of the fields even for long pulses.
