<p>A slab-shaped laser medium 1, excited by a lamp 2 and cooled by a flow of water 5, is supported at side surfaces 12 by support members 5. Deviations 52 from a smooth plane surface are formed at an inner surface of the support members 5, facing the slab, or at a back surface. The deviations, in the form of grooves or concavities, can be used to control the temperature distribution of the laser medium. They may provide a coolant path, e.g. for a flow of water. The distribution of pitch, area and/or depth of the deviations can be varied in the longitudinal and/or transverse direction of the laser medium 1.</p> |
