| Abstract: | The single-mode squeezed coherent states and their fundamental properties are discussed. Based on the modified effective Hamiltonian for the atom-field system, the state of the system is derived by means of matrix. A new scheme is presented to generate superposition of squeezed coherent states through non-resonant of degenerate V-type three-level atoms with single-mode cavity field. Controls of the squeezing direction of single-mode squeezed coherent states in the light field are also discussed. |
