Abstract
The performance of an RF excited gas laser having a discharge region with a generally curvilinear orthogonal cross-section, the shorter of the two dimensions of the discharge region cross-section being the spacing between non-conductive sidewalls which collisionally cool the discharge and are rotatable for guiding laser light, is enhanced by excitation field shaping. The field shaping includes use of a non-conductive member disposed between a high voltage field establishing electrode and a sidewall of the discharge region.
