摘要：

The effect of quantum fluctuations of the pump on the quantum phase properties of the signal mode in the parametric down-conversion process is considered. The Pegg-Barnett hermitian phase formalism is used to calculate the joint phase probability distribution and the phase variances of the two modes. The time evolution of the field state is obtained by means of numerical diagonalization of the interaction hamiltonian. The results are illustrated graphically and compared to those for the ideal squeezed state.
