| Zusammenfassung | It is shown, that diffusion of saturated gain (e.g. diffusion of population inversion in lasers) causes, or/and enhances modulational instability of light field patterns. In case of a subcritical system (e.g. in lasers with saturable absorber) the enhancement of modulational instability stabilizes spatial solitons. The predictions are made for general case of nonlinear optical systems, and are illustrated by numerical simulation of laser with saturable absorber. |
