چکیده
Comparative studies of characteristics Bessel and "perfect" vortex beams with a topological charge 9, created using binary silicon axicon "holographic" diamond continu-ous profile at wavelength 141 ?m, are carried out. Beams linear radial polarization investigated. An example the use perfect radially polarized beam for excitation plasmon-polaritons on cylindrical conductor is given.

Axicon Gaussian Laser Beams
If a laser beam is to have radial transverse polarization, the transverse electric must vanish on the symmetry axis, which is charge free. However, we can expect a nonzero longitudinal electric field on the axis, considering that the rays of the beam that converge on its focus each has polarization transverse to the ray, and hence the projections of their electric fields onto the axis all have ...
متن کاملGeneration of high quality tunable Bessel beams using a liquid-immersion axicon
By immersing a conventional glass axicon in index-matching liquid, we generated high quality, tunable, quasi non-diffracting Bessel beams. The aberrations resulting from the roundness of the axicon tip are minimized when a large base angle is used in liquidimmersion. This configuration also allows coarse and fine tunability through changing the liquid and adjusting the temperature, respectively...

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Efficient generation of a perfect optical vortex by using a phase optical element
We consider generation of a perfect optical vortex by three elements: (i) amplitude-phase element with its transmission being proportional to the Bessel function, (ii) optimal element with the transmission proportional to the sign of the Bessel function, and (3) helical axicon. Maximal intensity of light on the ring is shown to be achieved by using the optimal element. Thickness of the light ri...
