Growth of a new nonlinear optical crystal Ba2Be2B2O7 by TSSG method
In this work, a new nonlinear optical Ba2Be2B2O7 crystal was grown by top-seeded solution growth method using BaB2O4-BaCO3-NaF fluxes. The differential thermal analysis curve and a typical angle-tuned curve of Ba2Be2B2O7 crystal were also investigated. The measured ultraviolet absorption edge of the title crystal was found to be about 215 nm.
