A new approach to estimate refractive index, electronic polarizability, and optical basicity of binary oxide glasses

Interaction parameter A proposed in Yamashita-Kurosawa’s theory of dielectric constant, has been calculated for numerous binary oxide glasses on the basis of polarizability of oxide ion determined from refractive index. However, there are only a few reports on the multi-component oxide glasses system, especially BaO-Bi2O3-B2O3-SiO2 glasses system (G-BBBSO). Bismuth/barium-containing crystals have attracted much attention in application of material engineering because of their importance for the development of nonlinear optical (NLO) information processing technology. Compared to crystals, glasses have shown many advantages in the material engineering, such as easier shaping in casting procedures, low production cost and high thermal and chemical durability. Prompted by these interests in application of material engineering, we reported new data of interaction parameter of BaO-Bi2O3-B2O3-SiO2 glasses system (G-BBBSO) for the different wavelength range (480, 546.1 and 643.8 nm)

Étude Expérimentale

Using a Michelson interferometer coupled to a stabilised He–Ne laser, we measured the change of the refractive index of liquid CS2 along two isotherms, 273.15 and 298.15 K for pressures up to 140 MPa. Results show that the classical Lorentz–Lorenz equation versus the pressure varies linearly, as predicted by classical theory. Results also show that for liquid CS2 the experimental value of (8.4 ± 0.5) × 10−24 cm3, for the electronic polarizability in the range studied, is constant with pressure and temperature. Our experimental value of 8.74 × 10−24 cm3 for the electronic polarizability agrees with that found in the literature.

Analytical Expressions

In this article, we introduce a new approach to receive general solutions which describe all of the properties of the light propagating across optical uniaxial crystals. In our approach we do not use the conception of refractive index ellipsoid as being done in references. The solutions are given in analytical expressions so we can handly calculate or writing a small program to compute these expressions.
