Abstract

For continuous or long pulse ultraviolet metal ion laser operation the thermal energy charge transfer provides a highly efficient excitation mechanism. Due to high density of fast electrons, hollow cathode discharges are ideal sources to excite such lasers. A discharge arrangement called the segmented hollow cathode discharge (SHC) combines the advantages of the classical and the earlier high voltage hollow cathode construction. Besides the focusing and oscillation of fast electrons the discharge is restricted to the active volume of the laser. The increased voltage enhances the ionization and the sputtering of the metal, which has an easy access into the active volume. The SHC proved to be the most efficient discharge to excite UV lasers.
