Abstract

The plane-wave dynamics of 3ω→2ω,ω subharmonic optical parametric oscillators containing a second-harmonic generator of the idler-wave ω is analyzed analytically by using the mean-field approximation and numerically by taking into account the field propagation inside the media. The resonant χ(2)(-3ω;2ω,ω):χ (2)(-2ω;ω,ω) cascaded second-order nonlinearities induce a mutual injection locking of the signal and idler waves that leads to coherent self-phase locking of the pump and subharmonic waves, freezing the phase diffusion noise. In case of signal-and-idler resonant devices, largely detuned subthreshold states occur due to a subcritical bifurcation, broadening out the self-locking frequency range to a few cavity linewidths.
