K. Otsuka et al., NONRECIPROCAL GAIN FLOW, CLUSTERING AND CHAOTIC ITINERANCY IN ANTIPHASE INTRACAVITY 2ND-HARMONIC GENERATION, Optics communications, 112(1-2), 1994, pp. 71-74
Antiphase periodic states in a passive Q-switching regime of multimode
intracavity second-harmonic generation are investigated theoretically
, paying special attention to nonlinear interaction between orthogonal
ly polarized modes and the destruction process of antiphase periodic s
tates involving large oscillating modes. A nonreciprocal gain flow amo
ng the two polarizations, clustering into antiphase periodic modes and
chaotic modes, and chaotic itinerancy among attractor ruins of destab
ilized clustered states are found in numerical simulations.
