A method and apparatus is described for reducing the gas consumption rate by controlling the gas composition in a repetitively pulsed high pressure and/or high energy density TE CO2 laser. Detrimental gas species formed in the discharge are removed by chemical reaction in the gas phase and the reaction products are removed by a trap in a recirculator loop. In particular, the primary detrimental species is oxygen, the reducing gas added to remove this is hydrogen or deuterium and the resulting oxides of hydrogen or deuterium are removed by a molecular sieve.
