Abstract
Abstract The invention provides for producing stimulated infrared emission, an iraser, by means of an electric discharge in a gas mixture partly consisting of carbon dioxide in which the discharge space is closed at one end by a concave metal mirror and at the other end by a coupling-out window which covers the whole cross section of the discharge space and also acts as a reflector, according to the invention, this window consists of a plate of zinc selenide which is coated on the discharge side with a few reflection-increasing layers and on the outer side with a reflection-decreasing material.
