Abstract

Gas laser, particularly carbon dioxide laser, with a component-free gas dharge chamber between high voltage electrodes, with a beam of two resonator end mirrors multiply folded between facing reflectors and with openings of the outwardly sealed gas discharge chamber permitting the inflow and outflow of gas. A gas laser with the aforementioned features is so constructed for the purpose of increasing its efficiency, that there is a continuous gas flow in the gas discharge chamber and that the gas flow direction is parallel to the longitudinal axis of the component-free gas discharge chamber located between the reflectors.
