Abstract
In a gas laser (1) with a laser gas circulation path (5) in which a fan (4) conveys the laser gas (6) through a laser discharge space or tube (2) and a cooling system (3a, 3b), the gas throughput is increased by a bypass (8) of the laser discharge space (2). In the bypass may be a filter, cooler and catalyst for treating that portion of the laser gas flowing therethrough. The volume of gas diverted through the bypass may be adjusted to improve the efficiency of the laser.
