Some noclassical properties in electromagnetic field are investigated for the interaction of two-modes initially taken in coherent-state representation with the three-level Ξ-type atom, such as squeezing properties and violation of the Cauchy–Schwartz inequality. The enhancement of field squeezing is found by selective atomic measurement. The Cauchy–Schwartz inequality is violated by the application of the classical field followed by detection in excited state.

In this paper, we study the nonclassical properties of the electromagnetic field resulting from the interaction of a three-level ∧-type atom with a two-mode field initially in the coherent state, such as squeezing properties and sub-Poisson statistics. We show that the squeezing can be enhanced by selective atomic measurement.
