Abstract

A laser is characterized by a glass gain medium which contains trivalent samarium Sm.sup.3+ ions and which, when optically pumped on one or a number of absorption bands to achieve excitation at or above the metastable .sup.4 G.sub.5/2 level, radiates light at a wavelength substantially corresponding to transitions from the .sup.4 G.sub.5/2 level of samarium.
