DIAGNOSTICS OF INCLUSIONS IN ZnGe[P.sub.2] CRYSTALS BY THE METHOD OF TERAHERTZ SPECTROSCOPY

Results of experimental investigations of the dispersion of the refractive index n(v) and of the absorption coefficient a(v) of a ZnGe[P.sub.2] crystal in the frequency range 0.3-1 THz are presented. Their comparative analysis is performed. The spectra obtained can be used for real-time diagnostics...

Description
Summary:Results of experimental investigations of the dispersion of the refractive index n(v) and of the absorption coefficient a(v) of a ZnGe[P.sub.2] crystal in the frequency range 0.3-1 THz are presented. Their comparative analysis is performed. The spectra obtained can be used for real-time diagnostics of the material quality that requires integral characterization. The most informative spectral range in which considerable differences between the absorption coefficients are observed is determined to be 400-800 [micro]m. Keywords: THz range, dispersion, ZnGe[P.sub.2], refractive index, absorption coefficient.
