ABSTRACT:
An improved laser pumping apparatus in which a plurality of generally spherical beads are disposed in pumping energy transmitting juxtaposition with the active outer surface of a laser element so as to be positioned between the active outer surface of the laser element and a pumping energy source. in a neodymium doped yttrium aluminum garnet laser element pumped by a flash lamp, the beads are made of silicon. The beads are approximately 50 to 100 microns in diameter and may be attached directly to the active outer surface of the laser element, such as by using a pumping energy transmitting adhesive, or the beads may be attached to an intermediate transparent or translucent pumping energy transmitting member such as a thin sleeve that fits over a laser element configured as a rod.
