Abstract

The effect of detuning on the squeezing obtained in a prototype model for squeezing, namely the degenerate parametric amplifier, is investigated. A squeezed minimum uncertainty state is only obtained in a set of variables related to the original variables by a time dependent transformation. The required transformation is obtained using a symplectic decomposition of the dynamic evolution matrix.
