An Ultraviolet Faraday Rotator Glass.
Abstract
A Faraday rotator glass composition based on a fluoride glass, phosphate glass, fluorophosphate glass or a mixture there of is dope with a lanthanide in concentration sufficient to provide a Verdet constant above at least 2870 deg/Tesla-meter (1 MIN/CM-Oe) x (1.667 x 10 (exp 4) = 1 deg/Tesla-meter and optical transmission above at least 50 percent in a 25mm thick polished glass sample at least at one wavelength in the 200 to 400 nm wavelength region. The faraday rotator glass also includes monovolent non-lanthanide cations such as Na, Li, K or mixtures there of in a concentration sufficient to provide a Verdet constant above at least 2870 deg/Telsa-meter and optical transmission above at least 50 percent in a 25mm thick polished glass sample at least at one wave-length in the 200 to 400 nm wave-length region
