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

关键词: nonlinear squeezed one-photon state, amplitude-squared squeezing, sub-Poissonian behaviour, phase probability distribution
