Abstract
An ion laser includes a magnetic field source to generate an axial magnetic field in one region and transverse field components outside the region, the magnetic field source being shorter than the discharge channel of the laser. Axially spaced permanent magnets in the proximity of the discharge channel are adapted to the laser structure and can include magnetic rings or ring structures. The magnets are preferrably adjacent the cathode end of the discharge channel.
