Abstract: The experimental results of the external electric field dependence of near infrared transmission spectrum in Al2O3 ultrafine crystals are reported. It was found that the relative transmission change at 870 nm increases linearly with the applied electric field at high fields.

Key words: Al2O3 ultrafine crystals, near infrared transmission, external electric field
