Abstract: The theory of formation of photodeflection signal in the dense layer of chiral and achiral carbon nanotubes by irradiation of polarized modes of Bessel light beams was investigated. For the first time the solution of the heat equation was obtained using integral transforms Fourier–Bessel and Laplace for a three-layer medium, which is irradiated with light polarization modes Bessel beams with an intensity distribution in space.

Keywords: photothermal transformation, photodeflection spectroscopy, chiral carbon nanotubes, Bessel light beam, energy dissipation, Bessel function, heat equation, Fourier–Bessel transformation, angle of photodeflection.
