ABSTRACT:
A transverse discharge excitation laser is disclosed which includes a dielectric structure (11, 13, 111, 113, 211, 213) for defining an elongated laser excitation cavity (27, 127, 231) suitable for containing a laser gas and maintaining a laser exciting discharge in the laser gas, and further includes opposing conductive electrodes (33, 41, 129, 133, 237, 245) adjacent the laser cavity. The electrodes are sufficiently small to produce a laser exciting discharge within a predetermined region of the laser cavity and to provide optimum efficiency for the desired mode of operation. The electrodes are particularly adjacent opposing walls of the cavity which have a width W, and at least one of the electrodes has a width which is less than the wall width W.
