Abstract

An XeCl discharge laser with a high-brightness corona preionizer using a segmented columnar SrTiO/sub 3/ dielectric is discussed. A high overall efficiency of 2.35% with a laser output energy of 350 mJ was obtained using a SrTiO/sub 3/ doorknob capacitor cut by a diamond cutter as the dielectric. These characteristics are almost the same value as that obtained with an UV-spark-preionized XeCl laser using the same laser tube.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
