The invention may be used in developing of submillimetric, infra-red, optical laser spectrum and other. The lead-out mirror relates to the devises, in which open resonators are used. A hybrid lead-out mirror, which used in the devise, consists of two mirrors. One of them is an aluminum mirror with a hole, the second one is semi-transparent one made of wire, which covers this hole. The mirrors are set at the certain distance one from the other. The technical result is that by changing mirror hole diameter it is possible to control the beam divergence and also to reduce requirements to wire fences production.
