Gas laser, in particular a carbon dioxide laser, having a gas discharge chamber between high-tension electrodes free from inserts, having a beam path of two resonator mirrors, the beam beeing folded many times between two reflectors placed opposite each other, and having openings in the gas discharge chamber sealed to the exterior, said openings permitted the inlet and outlet of gas. A gas laser having the above mentioned features is designed to increase its power so that a continuous gas flow occurs in the gas discharge chamber and at the direction of gas flow is parallel to the longitudinal axis of the insert-free gas discharge chamber between the reflectors.
