ABSTRACT:
A laser having a deflector in which bypass gas is separated from a cathode and the local discharge region around the cathode, and in which the bypass gas has a relatively long open passage around the deflector to the cathode. The deflector has an open end surrounding at least a portion of the cathode and an aperture and having an aperture and a raised shoulder connected to the end of a laser tube. The aperture is aligned with the discharge bore of the laser tube with gas bypass bores outside of the aperture enclosed by the shoulder. The anode end of the laser tube may also have a deflector which is an annular washer having an aperture and a raised shoulder. The washer has a diameter nearly as large as the anode in which it is mounted.
