Abstract
The invention concerns a travelling wave laser and has application to the reduction of the divergence of laser beams. The electrodes between which the travelling electric discharge for the excitation of the amplifier gas takes place have a cross-section in the shape of two polished rounded-off points facing each other, so as to prevent spurious reflections of light towards the discharge zone and to reduce the divergence of the output beam which is converged by means of a simple optical system.
