Description

Radially and axial polarized beams can be generated by superposition of orthogonally polarized Hermite-Gaussian-like beams which are equal in amplitude. The DOE which transforms Gaussian into Hermite-Gaussian modes was a plate with a phase step equal to half of the wavelength. The combination of the Hermite-Gaussian modes (1.0) and (0.1) gives us the Laguerre-Gaussian mode whose polarization strongly depends on the polarization orientation of the forming beams. Possible applications of these beams in surface plasmon setups are discussed.
