摘要: We demonstrate the collapse of a continuum transverse modes in self-imaging ring resonator that is photorefractively pumped. The resulting localized mode has an arbitrary location. results from placing saturable photorefractive gain and loss media spatially conjugate planes. position unstable under small cavity misalignments, it drifts across aperture while retaining its spatial form.
