Abstract: The paper deals with theoretical and experimental investigation of infrared radiation absorption in tellurium single crystals. Optical attenuation coefficients ($\alpha_\mathrm{min}=0.2$ cm$^{-1}$ and $\alpha_\mathrm{max}=4.1$ cm$^{-1}$) were recorded for ordinary and extraordinary polarized radiation, respectively, at a wavelength of $\lambda=10.6$ mkm of carbon dioxide laser radiation. Optical transmission of the tellurium samples was determined for arbitrary polarized radiation depending on the propagation angles against the optical axis of the crystal.

Keywords: tellurium single crystal, anisotropic absorption, infrared radiation, polarized wave, $\mathrm{CO}_2$ laser.
