Abstract

The mean-field model of a degenerate optical parametric oscillator (DOPO) is known to exhibit pattern formation at threshold for negative signal detunings. On the other hand, there are two stable, equivalent, spatially-homogeneous solutions which may be connected by domain walls for positive detunings. By using input pump beams formed by Gauss-Laguerre modes with zero radial index and azimuthal index m≠0, single- and multiple-domain walls can be asymptotically trapped in the signal output beam. It is shown that several configurations of regularly and irregularly spaced domain walls can be generated with either m = 1 or m = 2.

On the other hand, there are two stable, equivalent, spatially-homogeneous solutions which may be connected by domain walls for positive detunings. By using input pump beams formed by Gauss-Laguerre modes with zero radial index and azimuthal index m≠0, single- and multiple-domain walls can be asymptotically trapped in the signal output beam.
