Radially and azimuthally polarized nonparaxial Bessel beams made simple.
We present a method for the realization of radially and azimuthally polarized nonparaxial Bessel beams in a rigorous but simple manner. This result is achieved by using the concept of Hertz vector potential to generate exact vector solutions of Maxwell's equations from scalar Bessel beams. The scalar part of the Hertz potential is built by analogy with the paraxial case as a linear combination ...
متن کاملGeneration of radially polarized beams with an image-rotating resonator.
We show how a passive image-rotating optical resonator can be used to convert a linearly polarised, lowest-order Gaussian beam into a radially polarized beam. The image and polarization rotation of the cavity removes the frequency degeneracy of the modes, making it possible to select the radially polarized mode by cavity tuning. With the addition of gain, the same cavity should operate as a rad...
متن کاملGeneration of Radially Polarized Beams Using Optically Patterned Liquid Crystals
Radially polarizing liquid crystal (LC) devices aligned optically were investigated for applications in laser technology. Presently, radially polarized beams are generated through complex laser resonator configurations or buffing of LC alignment layers. Optically aligned LC devices offer several advantages over these methods, including their simple fabrication, low cost, high laser damage thres...
متن کاملGeneration of non-diffractive Bessel beams by inward cylindrical traveling wave aperture distributions.
The focusing capabilities of an inward cylindrical traveling wave aperture distribution and the non-diffractive behaviour of its radiated field are analyzed. The wave dynamics of the infinite aperture radiated field is clearly unveiled by means of closed form expressions, based on incomplete Hankel functions, and their ray interpretation. The non-diffractive behaviour is also confirmed for fini...
متن کاملPolarization singularities of focused, radially polarized fields.
The state of polarization of strongly focused, radially polarized electromagnetic fields is examined. It is found that several types of polarization singularities exist. Their relationship is investigated, and it is demonstrated that on smoothly varying a system parameter, such as the aperture angle of the lens, different polarization singularities can annihilate each other. For example, the ev...
