The solid state laser has a solid state material for generating a laser beam and associated pump source. The pump radiation is beamed into the solid state material and the arising heat conducted away. The solid state material is subdivided into several individual plate-shaped solid state elements (1), arranged one on top of the other. Intermediate plates (2) are arranged in between adjacent plates for distributing and/or conducting away the generated heat. A heat sink is arranged on the outer surface of the upper and lower plates. USE/ADVANTAGE - For 100 W solid state laser. Avoids adverse effects of thermal disturbances. Is more compact than gas laser.
