Gs. Agarwal, STRONG-COUPLING INDUCED SPLITTING OF DYNAMICAL RESPONSE OF THE OPTICAL PARAMETRIC OSCILLATOR, Physical review letters, 73(4), 1994, pp. 522-524
A new quantum regime of the optical parametric oscillator is reported.
The strong coupling between the single photon pump mode and the signa
l-idler modes leads to splitting of the transmission resonance of a ca
vity containing an optical parametric oscillator. The characteristics
of the transmission doublet are obtained.
