Abstract:

The application of a variation of intensity method using static uniaxial compressive stress and polarized light to measure stress-induced birefringence in the infrared wavelength region approximately 1 to 12 microns is described. The measurements were made at 296 K for the following materials KCl, KBr, KI, NaCl, LiF, ZnS, ZnSe and SrF2, CaF2, MgF2 and a chalcogenide glass TI-1173 for the alkali halides the values of the stress optic coefficients obtained are in the range approximately 1 to 4 Brewsters, while for the non- oxide glasses values of 9 to 14 Brewsters were measured. Comparisons of measurements from experiments with a theoretical model which predicts the wavelength dispersion of stress birefringence cannot be fitted better than a factor of approximately 2.
