Abstract

It is shown theoretically, that observed in experiments the strong low threshold feedback in the resonator with a high pressure gas (Xe) cell of the CO₂ laser, in which the frequency interval between axial modes is equal to frequency Stokes shift at Stimulated Brillouin Scattering (SBS) in Xe, can arise owing to nondegenerate four-wave mixing in a gas cell on generated as at SBS running phase gratings.
