Abstract
Abstract Laser glass host compositions for effective lasing amounts of Nd2O3 are disclosed, the host compositions comprising TeO2, BaO and Li2O in certain molar amounts. Methods of making highly effective laser articles, including laser rods, also are disclosed. The new use of the above-described TeO2/BaO/Li2O glass compositions for forming laser articles, are disclosed, the new use including forming laser articles from glasses, pumping the laser articles to provide an energy inversion, and lasing the pumped articles.
