摘要: Formation of one-dimensional spatial structures in degenerate optical parametric oscillation due to diffraction effects is discussed and their analogy with parametrically excited localized studied hydrodynamics illustrated. It shown that, when the emergence roll paterns inhibited by cavity constraints, form bright or dark solitary waves for signal field may be generated appropriate detunings pump from a resonance. The exist bifurcation supercritical are stable close threshold, whereas spontaneously arise subcritical case large below threshold modulational instability homogeneous state.
