Permissible overheating of the gaseous medium in a gas-flow laser excited by fission fragments from uranium nuclei

摘要

The limits on the permissible overheating of the gaseous mixtures in gas-flow lasers excited by uranium-nuclear-fission fragments are examined. The first limit is associated with the possibility of growth of a heat-removal zone near the walls and the second arises from the need to preserve the cavity stability.
