Using the numerical method, we study the collapse and the recovery of atom, the anti-bunching and the amplitude-squared squeezing of two-level atoms interacting with nonlinear coherent field. The variations of the quantum properties with the parameter of light field, the initial state of the atom and the Lamb-Dicke parameter of the nonlinear coherent state are discussed.-
