Abstract
Abstract The present invention relates to an apparatus and process for achieving amplification of radiation from an excited, chemically reacting mixture by initiating chemical reaction of the mixture adjacent to an optical cavity and quickly flowing the mixture transversely through the cavity while the radiation interacts with the excited molecules of the mixture. Tuning and focusing of the optical cavity or the reflection chamber is effected by varying the placement and curvature of cavity defining reflectors. Output light energy is removed from the optical cavity by a separate reflector selectively movable into the path of the reflecting radiation.
