K. Staliunas et Vj. Sanchezmorcillo, LOCALIZED STRUCTURES IN DEGENERATE OPTICAL PARAMETRIC OSCILLATORS, Optics communications, 139(4-6), 1997, pp. 306-312
We show spatial localized structures in degenerate optical parametric
oscillators. We find numerically stable localized structures in the fo
rm of single localized stripes and of a double-stripe form in case of
one spatial dimension. In two dimensions rotationally symmetric spots
and localized rings are demonstrated.
