Photon statistics under multi-quantum interaction of generalized two-level system with strong squeezed electromagnetic field

Interaction of squeezed light with a two-level system having a degenerate excited level is discussed. The dependence of relative fluctuation of the electromagnetic field density $\eta$ as function of squeezing parameters and process photon number $n$ are found. It is shown that when the field intensity is slow and $n$ is small, the value of $\eta$ weakly depends on the method of squeezing. The value of $\eta$ becomes larger under the phase squeezing than under the amplitude squeezing when the field intensity and $n$ increase.
