摘要：
The long-time behaviour of the phase quantum fluctuations in the field produced by the parametric down-conversion with a quantum pump is studied. It is shown that if the pump is initially in a coherent state the phase variances for both the signal and the pump modes show collapses and revivals in their long-time evolution.
