Abstract :
Crystals of Sr3NbGa3Si2O14 (SNGS) with ordered langasite structure were grown using the Czochralski (CZ) method along the Cartesian X-axis [110]. The as-grown crystals exhibit high optical quality and structure perfection. Giant optical rotation was observed by polarized microscope. Optical transmission was measured at various wavelengths between crossed polariser. Optical activities were obtained by TU1900 spectrophotometer and found SNGS crystals showed unusually large values of ρ.
