Abstract
This invention relates to thallium tellurite glasses possessing a high Verdet constant and high optical nonlinearity, as well as good visible and infrared transmission, making them suitable materials for the fabrication of active optical devices. The glasses consist essentially, expressed in terms of cation percent, of 5-74.5% TeO.sub.2, 0.5-20% SiO.sub.2, 4-50% TlO.sub.0.5, and 0-71% PbO, wherein PbO+T10.sub.0.5.gtoreq.25 %, TeO.sub.2 +SiO.sub.2 .gtoreq.25%, and TeO.sub.2 +SiO.sub.2 +TlO.sub.0.5 +PbO constitutes at least 65% of the total composition.
