The research aims to analyze second-harmonic generation from radially polarized laser beams in homogeneous plasma.
Derived radial and axial current density components using Lorentz force and continuity equations.
Established analytical expressions for SHG field amplitudes in the wave equation.
Performed Fourier-Bessel particle-in-cell (FBPIC) simulations to validate findings.
SHG field amplitudes show periodic oscillations along the propagation axis.
Detuning length is dependent on plasma density and laser parameters.
Radial and axial contributions to SHG are significantly enhanced near the beam axis.
