Tilted wave emission in optical parametric oscillators induced by a bichromatic pumping.
Tilted wave emission is found in a mean-field model of a degenerate optical parametric oscillator pumped by a bichromatic field with a frequency offset much smaller than the cavity free-spectral range. Tilted wave emission arises due to a nonadiabatic mechanism induced by the slow pump modulation, and disappears when either one of the two pump waves is blocked.
