Growth of α-BaB_2O_4 single crystals from melts at various compositions: comparison of optical properties

摘要

The conditions for growing bulk α-BaB_2O_4 single crystals from stoichiometric melts and high-temperature solutions as well as some associated problems are reported. The morphology of crystal, formation of inclusions and light scattering depending on crystal growth conditions are described. Comparative estimation of spectral characteristics and of the optical quality, as well as the damage threshold of crystal samples suitable for production of polarization devices of laser systems have been performed.
