ABSTRACT:
A hollow cathode laser comprises a cathode body which constitutes a part of a discharge envelope. The cathode body has a cathode hole coaxial with the body. It further has three anode holes which are through holes extending parallel to the axis of the cathode body and communicating with the cathode hole through slits, respectively. Three cylindrical anodes extend respectively through the anode holes and are spaced by a given distance from the inner surfaces defining the respective anode holes. The anodes have portions which protrude through the respective slits and which are positioned flush with the inner surface defining the cathode hole in the circumferential direction thereof.
