Abstract
A laser preionization electrode (15, 17) formed of a dielectric tube (16) of square cross-section enclosing an electrode (18) of circular cross-section, the electrode (18) being of a large diameter on the order of 6.35 millimeters. A pair of such electrodes (15, 17) are located on either side of a main electrode (11) in a laser with the result that longer length preionization electrodes may be constructed while eliminating alignment problems of the prior art.

Laser preionizer apparatus comprising:
- a dielectric tube of rectangular cross-section;
- and
- an electrode of circular cross-section disposed within said tube and having a diameter in the range of 3 to 9 millimeters.
A laser comprising:
- a housing having first and second opposing sides;
- first and second main electrodes mounted respectively on said first and second opposing sides;
- and
- first and second preionization electrodes mounted on either side of one of said first and second main electrodes, said first and second preionization electrodes each comprising a rectangular dielectric tube surrounding a conductive electrode of circular cross-section.
