RADIATION REFLECTION DEVICE FOR SOLID-STATE LASERS Russian patent published in 2020 - IPC H01S3/02 

FIELD: laser engineering.

SUBSTANCE: radiation reflection device for solid-state lasers has a pumping radiation reflector, an active element and pumping lamps placed inside it, and placed in a quantron, comprises focal planes arranged so that all radiation of the pumping source is collected in the region of location of the active element, increasing the power of the generated laser radiation. Reflecting coating consists of silver anodized aluminum of thickness from 0.2 mm to 1.5 mm, which is glued to base of plane-arc reflector of quantron.

EFFECT: technical result consists in providing the possibility of increasing the efficiency of reflection in the visible and near infrared part of the pumping spectrum and in the absence of the need for high-precision mechanical processing of the base of the plane-arc reflector of the quantron.
