Influence of Stark shift and Kerr medium on the phase properties in two-photon processes — •M. Abdel-Aty1, A.M Abdel-Hafez2, and A.S.F.

We have investigated the phase properties of the field in the two-photon Jaynes-Cummings model, taking into account the level shifts produced by Stark effect with an additional Kerr medium using the phase formalism of Pegg and Barnett. The results for the time evolution of the phase probability distribution and the phase fluctuations are obtained. The effect of Stark shift on the phase properties in both the absence and presence of a Kerr medium is analyzed. Phase localization is found for certain choice of the parameters.
