Investigation of Optical and Structural Homogeneity of Ca₄GdO(BO₃)₃ Single Crystals

Optical and structural homogeneity of undoped Ca₄GdO(BO₃)₃ crystals grown from the melt by the Czochralski method in the [010] direction was investigated by spectroscopic measurements and using an automated spectropolarimeter over the entire area of the samples in the wavelength range between 660 and 800 nm. A fair to good optical quality of the investigated crystals was found. Those results are compared with chemical etching experiments.

Keywords: Ca4GdO(BO3)3 crystals, optical homogeneity, chemical etching
