Abstract

Photon distribution function, means and dispersions are found explicitly for the nonclassical state of light which is created from the photon--added coherent state α,m due to a time--dependence of the frequency of the electromagnetic field oscillator. Generating function for factorial momenta is obtained. The Wigner function and Q--function are constructed explicitly for the excited photon--added coherent state of light. Influence of added photons on known oscillations of photon distribution function for squeezed light is demonstrated. oscillator are considered.
