This paper introduces the squeezed photon-added coherent states defined by |α,m,ξ〉=S(ξ)a+m|α〉up to a normalization constant,where |α〉is a coherent state,m an integer and S(ξ) a squeezing operator.It studies the mathematical and physical properties of such states.Phase squeezing character of the fields in such states is demonstrated.The conclusion shows that the more field quadrature x is squeezed,the larger squeezing parameter becomes.
