摘　　要：Parametric down-conversion is a useful method to obtain non-classical state in quantum optics. （1） An analytical solution to the Fokker-Planck equation of non-degenerate optical parametric amplification （NOPA） for generation of squeezed light is presented. The maximum intra-cavity compression of squeezed light derived from the analytical solution is 1/16 （vacuum fluctuations 1/4）. To compare it with the previous 1/8 of degenerate optical parametric amplification （DOPA）, it seems that squeezing for NOPA is superior to DOPA.Parametric down-conversion is a useful method to obtain non-classical state in quantum optics.
