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.de608621patent1987-3716873
