OPTICAL NOISE SUPPRESSION AND POWER ENHANCEMENT IN POSITIVE COLUMN LASERS USING MAGNETIC FIELDS ABSTRACT OF THE DISCLOSURE A technique for simultaneously improving the optical noise and output power performances of positive column lasers, and in particular metal vapor lasers such as helium- cadmium lasers. A magnetic device is positioned either in contact with or in the immediate proximity of the laser tube envelope. The magnetic device is capable of producing a magnetic field transverse to the optical axis of the laser tube in the vicinity of the cathode discharge glow or at the discontinuity between the positive column discharge glow and the cathode discharge glow.
