We present the analytic expressions for different types of quantum interference effects in coherent instantaneous state quantum system, and discuss the behaviors of the optics and quantum interference, respectively. The important role that the geometrical phase plays in quantum interference is analyzed in detail for the first time. It is demonstrated theoretically that the measurement of the geometrical phase can be realized by appropriately choosing the pulse area of the pump field. The valid control of the quantum interference is achieved by manipulating the chirped pump field.
