Abstract: The phenomenon of occurrence of photodeflection signal in gyrotropic superlattice by irradiation of Bessel light beams (BLB) was investigated. It was found that the rate of energy dissipation TE-mode BLB essentially depends on the radial coordinate $\rho$, normalized coordinate $xw = x / w_0$. BLB taper angle $\alpha$, as well as the frequency of the amplitude modulation $\Omega$ BLB.

Keywords: photodeflection responce, gyrotropic superlattice, Bessel light beam, energy dissipation rate, amplitude of the photodeflection signal, Bessel function, heat equation.
