Description

Bismuth Silicate Crystal Substrates Description 

Bi12SiO20 bismuth silicate crystal substrate, abbreviation BSO substrate, is an excellent material with highly efficient photoconductors with low dark conductivity that allows a build-up of large photo-induced space-charges.

BSO crystal is a good photorefractive crystal with a wide range of applications. It is a light yellow photoelectric/electro-optical crystal and a photorefractive crystal. It can be used in electro-optic readout optical memory (PROM), thin-film optical waveguide, photorefractive and phase conjugation.
