Spatial Dynamics of a Radially Polarized Terahertz Laser Beam with a Phase Singularity

Analytical expressions are obtained that describe the nonparaxial diffraction in free space of the TM01 mode with radial polarization of the field of the dielectric waveguide resonator of a terahertz laser during its interaction with a spiral phase plate with different topological charge (n). The ph...
