  • Magnetic polarization of tubular laser
    Patent number: 4035741
    Abstract: There is disclosed the magnetic polarization of a tubular gaseous laser device comprising a laser capillary tube with anode and laser end pieces, a cathode, a cathode envelope, and a gas exhaust stem for filling the device with a laseable gas. Magnetic polarization of the light output from the laser is achieved by applying a magnetic field to the lasing capillary and the rotation of the laser within the magnetic field to optimize the extinction ratio.
