The nonlinear squeezed one-photon states and their nonclassical properties

By virtue of the technique of integration within an ordered product (IWOP)of operators and the properties of the inverses of annihilation and creationoperators of f-oscillator, this paper obtains two new typesof squeezed operators and f-analogues of squeezed one-photon states, which are quite different fromones constructed by Song and Fan({Phys. Lett.} A {294} (2002) 66). Subsequently,some nonclassical properties of the states are investigated in detail.
