Electro-optical properties of the crystals of gadolinium molybdate (GDM) with neodymium addition

The article gives the results of research of changes in dielectric properties, tangent of loss and domain structure of GDM crystals with neodymium addition under the influence of external action. The dependence of domain boundaries position upon electric field action is defined. The domain boundaries form a diffraction grating with variable spacing and it enables to control the divergence of radiation. The crystals with controllable value of index and time-expanded transition to another phase can be used for scanning of laser radiation.
