Investigation of optical defects in dielectric crystals.

Scientific chief

Ph.D. Fedorov V.A.

The main purpose of this work is investigation of optical defects organization in crystals, in dependence of crystallization process condition. Three methods were used in experiment for defects investigation: interference method, polarization method and dispersion with low angle. The base result of the work is reconstruction, adjustment of Mah-Tsender interferometer and upgrade of experimental equipment with modern digital system for interferogram scanning and analysis, estimating of equipment sensibility, organization of test experiments sequence with laser dielectric crystals.
