A study of the noise spectra of cw zinc-ion lasers using hollow cathode and more conventional discharges is reported. It is found in the present work that the hollow-cathode mode of operation has two very attractive advantages over previous discharge tube designs for use in zinc-ion lasers: First, the noise on the output beam is at a very much lower level; second, there is a substantial improvement in gain per unit length on transitions from high-lying states of the ion.
