Abstract
A CO.sub.2 gas laser is equipped with a gas mixture control arrangement which introduces into the interior of the laser, of the constituent component of water, only hydrogen, in such amounts based on the instantaneous humidity of the gas mixture that the dew point of water vapor resulting from the combination of the thus introduced hydrogen with incidental oxygen present in the laser interior as an incident to the operation of the laser is maintained within a predetermined range.
