Holographic feedback features at non-monochromatic radiation of lasers with self-forming four-wave mixing

Abstract

It is shown theoretically, that the axial modes of radiation in PC mirrors at four-wave mixing with a feedback without selection in the resonator result to generation of a direct wave and suppress generation of a backward wave with the conjugated wave front. It is established, that due to axial modes in self-starting lasers the holographic feedback is carrying out the function of the output mirror of the resonator forms. The large role of polarization discrimination at Faraday effect in PC mirrors at four-wave mixing with a feedback and in self-adaptive lasers is marked.
