Abstract Scope |
Transparent polycrystalline materials like oxide ceramics are firmly established in optical–structural applications such as high toughness windows and are increasingly important in lasers and other photonic devices. Light transmission, absorption and diffraction heavily depend on their microstructure. We present modelling studies that demonstrate the effects of parameters such as absorption type (Lorentzian or Gaussian), scattering regime (Raleigh–Gans–Debye or Rayleigh), and optical path length on transmission spectra. We use the model to interpret experimental measurements and elucidate the effect of crystalline anisotropy, grain size on optical properties of the ceramics. |
