Optical properties of significant acousto-optic crystals

Authors:

Muşinschi, Valeriu; Muşinschi, C; Sîrbu, Nicolae; Caraman, Mihail

Summary:

Results of the investigation of spectra in the energy ranges of fundamental absorption of PbMoO4 crystals in two radiation polarizations (EC4) and (E⊥ C4) of incident light in the 77-300 K temperature range are presented. Possibilities of the interpretation of particularity of absorption spectra on the basis of the proposed band structure are examined. Analysis of measurement results for reflection spectra of paratellurite TeO2 and wulfenite (PbMoO4) crystals within the interval 50-1000 cm-1 is presented. The Kramers–Kronig method is used to interpret the peculiarities of reflection spectra. The calculus of reflection spectra is made by the multioscillation model. The interest in the study of the optical properties of TeO2 and PbMoO4 crystals is determined not only by the fundamental physical mechanisms present in these materials but also by a wide spectrum of possible applications in high-speed acousto-optic devices that perform spatial, temporal, and spectral modulation of optical beams. A description of experimental results of studying the optical properties of tetragonal TeO2 (class 422) and PbMoO4 (class 4/m) crystals is given. The phenomena usually studied to obtain information on the optical properties of crystals are absorption and reflection in a large wavelength range.
