  • Minimum inductance laser head for pulsed transverse discharges without wall tracking
    Patent number: 4665526
    Abstract: Four broad metal vanes form two pairs of contoured metal sheets arranged symmetrically about orthogonal planes of a discharge device to provide a uniform and properly shaped electric field for a discharge region between opposed slab electrodes situated between upper and lower pairs of the vanes in proximity to electrode edges. The electrodes border the region inside a housing having dielectric wall portions interposed between broad surface portions of the vanes and the discharge region located intermediate the electrodes. The electric field is delineated by the vanes so as to inhibit discharge tracking on the wall portions bounding the discharge region.
