ABSTRACT:
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 or molecular sieve capable of removing the unwanted gases or vapors. A molecular sieve comprised of zeolite with the appropriate intermolecular spacing is especially preferred.
