Abstract
Sensitizer impurities absorb a portion of pump radiation in a laser generator that is not absorbed by the activator impurity. The sensitizer transfers the otherwise wasted radiation to the activator impurity. Mn.sup.+2, UO.sub.2.sup.+2 and Ce.sup.+3 are examples of sensitizer ions. The foregoing sensitizer ions may, in turn, be sensitized by other impurities, known as cosensitizers to further utilize pump radiation.
