LASER MIRROR(VARIANTS) Russian patent published in 2007 - IPC G02B5/08 

FIELD: the group of inventions refer to laser technique and may be used in mirror elements of laser resonators and in arrangements for transmission of laser radiation.

SUBSTANCE: the laser mirror has two identical, not communicating between themselves, symmetrical priming contours of heat-carrying agents located between the front plate on whose exterior side a reflective surface is fulfilled, and the rear plate on both sides of the diagram located in the symmetry plane of the arrangement. Each of the priming contour of the heat-carrying agents is fulfilled in the shape of in-series located, beginning from the diagram, a driving collector, a draining collector, a heat exchanger whose exterior surface adjoins to the inner surface of the corresponding plate. The cavity of the driving collector is connected via channels passing through the draining collector with the heat-exchanger which is connected with the cavity of the draining collector. In the second variant of the arrangement the reflective surfaces of the laser mirror are fulfilled on the exterior sides of the front and the rear plates. The heat exchangers are fulfilled in the shape of identical infiltration elements of the same sizes and forms correspondingly to the front and the rear plates.

EFFECT: reduces thermal distortions of the reflective surface and also increases the service term of the laser mirror.
