This solution is applied to calculate the fields of a radially polarized Laguerre–Gaussian laser beam. It shows that although both formalisms are correct ways of finding electromagnetic solutions, as the beam waist size is less than a laser wavelength, the longitudinal electric field near the ...
Attosecond EUV Bessel-Gauss beam can now be generated through propagating an annular high harmonic source produced by the interaction of a strong laser with atomic gas. Mingxuan Li Xiangyu Tang Dajun Ding ArticleOpen Access06 May 2025 A chip-integrated comb-based microwave oscillator ...
Such multichannel polarization multiplexing can be used for dynamic vectorial holographic display and can provide triple protection for optical security. The concept is appealing for applications of arbitrary spin to angular momentum conversion and various phase modulation/beam shaping elements....
When l = 1, Equation (5) describes the electric field of a radially or azimuthally polarized beam with annular intensity distribution. Light beams with radial and azimuthal polarizations are the most well-known cylindrical vector beams with phase (scalar) and polarization (vector) singularities. ...

Light waves are electromagnetic waves, which means they consist of both electric and magnetic fields that oscillate perpendicular to the direction of wave propagation. The polarization of light is determined by the orientation of the electric field vector. 偏振片(Polarizers) Linear Polarizations Polarizi...

A birefringent or anisotropic crystal is one where the two components of light of the polarised beam have unequal refractive indices (η) and hence the unequal velocity inside the crystal. This causes a phase lag between the two components of polarised light. When the light emerges out in the...
