Abstract
A laser tube made of electrically insulating ceramic material, e.g., BeO, is formed of dry pressed and fired segments brazed together and with a chamfer or stepped area at the end of each segment adapted to interrupt the bore so as to prevent the establishment of a continuous electrically conducting layer in the tube bore.
