In this paper, the multi-photon field squeezing effects for the mixed absorptive-dispersive driven optical system in good cavity case is discussed. Under certain condition, for the single-photon case the squeezing effect of A1, one of the quadrature component of field, in the mixed systems is better than that in the pure absorptive systems. And for the two-photon case, the squeezing effect of A2, another quadrature component of field, may appear.
