This patent describes a laser comprising: means for defining an elongated laser cavity suitable for containing a laser gas and maintaining a laser exciting discharge in the laser gas. The laser cavity has a longitudinal dimension and a cross section perpendicular to the longitudinal dimension; and a pair of opposing electrodes disposed in the proximity of and extending along the laser cavity longitudinal dimension for providing a laser excitation field within the cavity and respectively having an electrode dimension that is generally parallel to a corresponding cross sectional dimension of the laser cavity. The electrode dimension of at least one of the opposing electrodes is less than the laser cavity cross sectional dimension. The electrodes produce a laser exciting discharge within a predetermined region of the laser cavity and providing for laser energy with optimum efficiency.
