Faraday Rotation of EY-1 Glass

Abstract

EY-1 os a terbium-silicate glass recently developed by Owens- Illinois. It offers great potential as a Faraday rotator-isolator in high power laser systems because of its high Verdet constant, V =-4.06 plus or minus 0.1 x 10 to the -2 power min/Oe-cm at 1.064 micrometer. This allows one to use shorter lengths of glass and lower magnetic fields than with other rotator glasses. The authors have measured V in this glass at 1.06 micrometer with fields up to 60 KOe and, in addition, the change in V with temperature and wavelength. The requirements that these numbers impose on the field, temperature and wavelength stability and uniformity are discussed.
