摘要：
We find explicit expressions for the variances in a single-mode superposed squeezed state as a function of a certain parameter. Formally, the parameter is given as a function of the mean free path (which can be measured experimentally) of the atoms of a material medium through which the natural light passes. Physically, this parameter is just the mean number of photons present in the coherent state of the mode under investigation. Some interesting new results follow as a consequence of using the P-representation of the density operator for the squeezed state of the mode.
