Abstract
Abstract AN APPARATUS AND METHOD FOR MAGNETICALLY SCANNING THE BEAM OF OUTPUT RADIATION FROM AN ELECTRIC DISCHARGE FLOWING GAS LASER ARE DISCLOSED. MAGNETIC STABILIZATION MEANS ARE USED TO NEUTRALIZE THE EFFECTS OF GAS FLOW ON THE DISCHARGE PLASMAS WHICH IS MAINTAINED AS A STRAIGHT LINE DISCHARGE IN A DEGENERATE OPTICAL RESONATOR. A VARI- ABLE INTENSITY MAGNETIC FIELD IS APPLIED TRANSVERSE TO THE DISCHARGE CAUSING MOVEMENT OF THE LASER MEDIUM WITHIN THE RESONATOR AND PROVIDING A CORRESPONDING SCAN OF THE OUTPUT LASER BEAM.
