We investigate the atomic inversion and field entropy evolution for the two photon Jaynes Cummings model assuming the atom and the field to be initially in the ground state and squeezed coherent state, respetively. It is shown that the field entropy which indicated correlation between the atom and the field maintains oscillations during collapse period. It is shown also that the Stark shift has an obvious influence on the magnitude of the field entropy and the wave package outlines of revivals.
