Abstract: The quantum properties of light in the system of three entangle atoms in the W-type states interacting with radiation fields in binomial states were studied by means of quantum theory. By means of the numerical method, the relations between the quantum properties of the system with the initial states of the W-type three entangled atoms and the parameters of binomial optical fields are discussed.

Key words: W-type state, three entangled atom, binomial state, quantum properties of light
