A means is provided for continuously purging deleterious contaminants including water vapor, ozone and organic vapors from the resonant cavity of lasers where the resonant cavity is characterized by a gap-space between the gain medium and the optical mirror at both ends of the cavity with each of the gap-spaces being disposed within an enclosed chamber where the contaminants tend to collect. This is accomplished by connecting the interiors of the gap-space chambers through tubular gas conduits with one or more canisters which contain a chemical desiccant...


In a laser of the type wherein the resonant cavity is characterized by a gap-space between the gain medium and the optical mirror at each end of said cavity and wherein each said gap-space is enclosed by a gap-space chamber subject to fluctuating temperature, the improvement which comprises means for removing gaseous or vaporous contaminants including water vapor, organic vapors and ozone from the areas within a said gap-space chamber with said means being comprised of: at least one canister having its interior interconnected by a tubular conduit with th...
