In this paper, we have examined the influence of the counter-rotating terms on the sque-ezing phenomenon of the field in the two-photon Jaynes-Cummings model by means of the non-relativestic quantum electrodynamics. We verified that the effect of the virtual photon field in-creases the squeezing. The relation between the degree of squeezing and the field frequency, the mean photon number and the atom-field coupling constant has also analyzed.
