Surface characterization of the photorefractive crystals CdAs_2 and ZnAs_2 using electroreflectance

摘要

Significant magnitude of the dual beam refraction and gyrotropic characterized CdAs_2 and ZnAs_2 monocrystals are observed. Nonlinear effects, for example self-inducted rotation of the plane of polarization, exist for these materials due-to crystals symmetry and connect with spatial dispersion. These crystals is very important for following applications: light modulator, frequency reduplicator, optical filters, lenses and polarize prisms for IR region of the spectrum.
