UV lasing was obtained with helical copper hollow cathodes. The output powers have been measured multiline (248--270 nm) for some helix geometries as a function of different discharge currents, Ne pressures, and mirror reflectivities. A maximum laser power of 580 mW has been obtained in a segmented discharge tube with a total active length of 1.2 m. Laser action was also observed at 780 nm with a power of 1.3 W. The discharge stability is superior to other arrangements.
