Abstract

This paper reviews the application of high voltage hollow cathode discharges as pumping sources of cathode sputtered lasers. Special attention is devoted to the segmented hollow cathode (SHC) electrode arrangement, which proves to be the best pumping source for metal ion lasers. The increased voltage, together with the special electrode geometry, which focuses the fast electrons and makes their oscillation possible between the opposing cathode surfaces, results in a proper excitation for efficient laser operation. Using the segmented hollow cathode discharge, increased gain, better efficiency, and lower threshold current were obtained, compared to the earlier discharge constructions. The high gain offers possibilities for continuous VUV laser operation as well. The properties of the segmented hollow cathode discharge have also been investigated by Monte Carlo simulation motion of fast electrons in the discharge.
