Abstract

In a laser device having at least one gas-purged laser resonator which is arranged in a purging gas circuit which has upstream of the laser resonator both a low pressure generator for generating a purging gas excess pressure in the purging gas circuit and, between the low pressure generator and the laser resonator, a cleaning device for cleaning the purging gas, the purging gas being air, according to the invention the purging gas circuit has downstream of the laser resonator between the laser resonator and the low pressure generator an intake opening which is permanently open towards the atmosphere, the purging gas pressure (p1) generated by the low pressure generator being greater than the atmospheric air pressure (p0).
