$The band structure of birefractive CdGa2S4 crystals$

The band structure of birefractive CdGa2S4 crystals

In this paper, we report on the spectral dependence of Δn=no−ne for CdGa2S4 single crystals for shorter and longer wavelengths than the isotropic wavelength λ0=485.7nm (300K). It was established that Δn is positive at λ>λ0 and it is negative in the spectral range λ
