Abstract
An improved acousto-optic device and method featuring an acousto-optic element having an alkali metal oxide-tellurite glass composition comprising at least 92 wt % tellurium dioxide and one or more alkali metal oxides selected from the group consisting of sodium oxide and potassium oxide. A process for decreasing the acoustic attenuation of the aforementioned glass composition by annealing is also disclosed.
