METHOD OF GENERATING STABILIZED QUASI-MONOCHROMATIC HIGH-INTENSITY INFRARED RADIATION Russian patent published in 2020 - IPC G05D25/00 H05B47/10 

FIELD: physics.

SUBSTANCE: invention relates to generation of infrared radiation and a method of generating stabilized quasi-monochromatic infrared radiation of high intensity. Method includes generation in a given spectral range of background radiation with a given high intensity. In the same spectral range, additional radiation is generated with intensity lower than that of background radiation. Background radiation is mixed with additional radiation and simultaneously their spatial integration is performed. Small part of the obtained total radiation is supplied to an optical negative feedback of the additional radiation. Fluctuation component of the total radiation is selected and the intensity of the additional radiation is adjusted to make the value of the fluctuation component of the total radiation minimal.

EFFECT: technical result consists in enabling generation of quasi-monochromatic infrared radiation, having simultaneously high values of intensity, energy stability and spatial uniformity.
