  • Laser with travelling wave excitation
    Patent number: 4166252
    Abstract: A pair of elongated electrodes are located in a common plane, separated from each other by an elongated gap. A gaseous medium capable of being stimulated to emit radiation by laser action is located in the gap. A discharge between the electrodes is initiated at a predetermined position by a pumping means which also produces an electrical field which decreases uniformly and monotonically from said predetermined position as the distance from this position increases, such that the discharge formative lag time increases uniformly and monotonically from said predetermined position.
