Current density in a nonlinear medium of carbon nanotubes under the action of diffraction free laser pulses

Abstract

Based on the spatial distribution of the electric field strength of diffraction-free extremely short Bessel and Airy–Bessel optical pulses, patterns of the temporal evolution of the current density in a nonlinear array of semiconductor carbon nanotubes with a spatial modulation of the refractive index are constructed. The dependences of the maximum value of the current density on the modulation parameters of the refractive index of the medium are established.
