Abstract
An optical laser pumping system comprises means for providing a highly collimated pump radiation beam propagating along an axis, and an optical element which forms a concave, frustro-conical reflecting surface which is coaxial to said axis and tapers in the direction of beam propagation from an entrance end of large cross section, into which said beam enters, to a distal end of small cross section which surrounds said axis in spaced relationship. The laser medium is positioned between said ends along said axis.
