abstract
The degenerate parametric oscillator (DPO) is analyzed with the nonlinear material treated quantum mechanically. The source of squeezing in the DPO is the same as in the two-photon correlated-spontaneous-emission laser (CEL) - the level coherence. In this sense, they are similar. The amount of squeezing in DPO is the same as in the two-photon CEL at two- photon resonance, but the gain in DPO is usually much smaller than that in the two-photon CEL at two-photon resonance.
