FIG. 2.

Number of fringes as function of rotation angle measured at for GLSO and TeLi glasses. The curves are fits obtained using Eq. (1).

FIG. 3.

Room temperature refractive index and absorption as function of wavelength for (a) GLSO and (b) TeLi glasses. Solid line is a simulation using the data of Yayama et al. (Ref. 20). The dashed line is a fit using the single-effective oscillator model described in the text. The uncertainty in refractive index is .
