METHOD OF OPERATING CLOSED-CYCLE CARBON DIOXIDE LASERS IN WHICH CARBON MONOXIDE IS USED TO PREVENT DEGRADATION OF PERFORMANCE

摘要

A method of operating closed-cycle carbon dioxide flowing gas lasers in which a gaseous mixture typically comprising carbon dioxide, nitrogen and helium is electrically excited to produce lasing action, wherein carbon monoxide is included in the gaseous mixture in amounts sufficient to substantially prevent degradation of performance relative to open-cycle performance.
