Quantum properties of a three-level atom interacting with two radiation fields

Abstract
The quantum-statistical model for a three-level atom interacting with two radiation fields is studied. The mean atomic occupations and photon numbers are obtained under different initial conditions of one coherent field and one chaotic field or both chaotic or coherent fields, with the atom in upper or lower states. Through numerical summation, it is shown that the effects of coherent sources and chaotic sources are different even for low intensities. Meanwhile the effects of detuning on this interaction are discussed.
