title: Spontaneous formation of symbiotic solitary waves in a backward quasi-phase-matched parametric oscillator.
abstract: We show analytically the existence of nondegenerate symbiotic solitary waves in quadratic media with absorption losses. We study these new solitary waves in the particular case of a backward quasi-phase-matching configuration. Our numerical simulations reveal that, when it is used inside a singly resonant optical parametric oscillator, this configuration leads to the spontaneous formation of new solitary waves.
