Abstract
A gas laser includes a control to modify the distribution of the intensity of the laser light over the laser beam cross section produced in the lasing gas within at least one laser tube by at least two electrodes and a voltage supply unit by means of which a voltage can be fed to electrodes. A discharge area forms in the lasing gas and this can be affected by adjusting the amplification profile of the laser over the excitation cross section of the laser tube.
