Abstract
Gas flow laser, in particular a laser through which the gas flows transversely, or through which it flow rapidly in an axial direction, which possesses a main gas circuit embracing the resonator and a circulating pump, together with an auxiliary circuit for continuously bleeding-off, conditioning and reintroducing a partial stream of the gas. The cost of the auxiliary circuit is reduced by connecting it to the main circuit upstream and downstream of the circulating pump, so that the full delivery head by the circulating pump is available for operating the auxiliary circuit. The supply of fresh gas can be introduced independently of the auxiliary circuit.
