Magnetically enhanced THz generation by self-focusing laser in VA-MCNTs

Physica Scripta, Journal Year: 2023, Volume and Issue: 98(8), P. 085506 - 085506

Published: June 26, 2023

Abstract Magnetically enhanced terahertz (THz) radiations are generated on account of the self-focusing laser beam in bunch anharmonic Vertically Aligned Metallic Carbon Nanotubes (VA-MCNTs) embedded non-conductive sapphire or silicon (SOS) substrate. The high-power Gaussian gets self-focused VA-MCNTs as initial power propagating is greater than its critical power. resulting interacts with and a result, electrons MCNTs experience nonlinear ponderomotive force to show oscillatory behavior resonant transverse velocity. It produces current which drives THz radiation generation. Enhanced generation noticed regions where becomes stronger. We have observed that an applied magnetic field, MCNTs, self-focusing, dimensions also pave way for enhancement normalized amplitude. anisotropic dielectric tensor presence externally static field helps enhance results shown (by beautiful graphs well supported by numerical simulation) present scheme indicate can play diverse significant role important applications medical photonics varying values various parameters. emitted has ability detect changes DNA human beings because frequency lie region molecular spectra corresponding energy not high enough damage ionization.
