Deskripsi
The effects of the following factors on the optical properties of langasite crystals was studied: the growth direction for crystals of stoichiometric composition (La3Ga5SiO14) obtained in a growth atmosphere Ar+O2; growth atmosphere (Ar and Ar+O2) for crystals of stoichiometric composition; initial composition of crystals for the crystals obtained during the same conditions of growing and post-growth treatment (annealing in vacuum and in air, UV- and γ - irradiation).
