Abstract: The phenomenon of the appearance of a photoacoustic signal in a layer of carbon nanotubes under the action of irradiation with Bessel light beams (BLB) is studied for the case of piezoelectric recording. It was found that an increase in the taper angle of BLB affects the frequency of occurrence of resonance peaks depending on the radial coordinate $\rho$.

Keywords: photoacoustic transformation, piezoelectric detection, dense layer of carbon nanotubes, Bessel light beams, energy dissipation rate, amplitude of photoacoustic signal, Bessel function, heat equation.
