Abstract The quantum fluctuations of the pump and signal waves are derived for degenerate parametric down conversion from a pump field initially in the squeezed state. It is found that, to the quadratic term, while the degree of squeezing of the pump wave decays gradually, that of the generated signal beam increases up to a maximum then decays.
