Abstract
This contribution presents birefringence spectra for orthorhombic YAlO3∶Ce single crystal in the region 2–5 eV. The spectra were measured by means of a reflection method of null ellipsometry and were compared with spectra of YAlO3:Nd determined from values measured in the region of lower energies (1·1–2·2 eV). We have found that there are differences between the spectra of YAlO3∶Nd and YAlO3:Ce which are most pronounced in thea-axis direction.
