Growth of Acousto-Optic Crystals for Applications in Infrared Region of Spectrum

摘要

Acousto-optic (AO) modulators, deflectors, filters offer convenience, reliability, compact size and fast speed in regulation of optical beams. So far there are only a few AO materials available for use in the long infrared region of spectrum. The major disadvantage of such AO materials is the extremely low acousto-optic figure of merit, which automatically results in high requirements on driving electric power and poor diffraction efficiency. It is expected that the materials that satisfy the requirements on the high efficiency are the crystalline compounds based on mercury, tellurium, lead and other heavy metals. In the present Report, we list Universities, Institutes and Laboratories in Eastern European countries capable of growth and characterization of the new crystals. Short description of the found Institutes and Laboratories is presented in the Report. Mailing and electronic addresses of the Universities and Institutes as well as of specialists responsible for the crystal growth are also included in the presentation.
