We report results of the studies of a new version of a hollow-cathode discharge, namely, a multiple hollow-cathode discharge. The geometry comprises a main cylindrical cathode, which defines the active laser volume, and a number of short cylindrical side cathodes arranged radially to the main cathode along its length. PLASIMO’s Drift-Diffusion module is used to describe numerically the new laser tube configuration and to demonstrate its advantages.
