ABSTRACT:
A device for optically pumping a solid state laser consisting of a rod of a laser material, and at least one light pumping source having a point form or shape characterized by a waveguide arranged between each pumping light source and the laser rod for coupling the pumping light into the rod. Preferably, the waveguides are either glass rods or a prism and the optical axis of the waveguide extends at an angle .delta. with a normal to a flat surface of the rod of laser material which angle .delta. has a relation of 2 arc sin (1
.sub.1) .ltoreq. .delta. < .pi./2 wherein n.sub.1 is the index of refraction of the light waveguide.
