Journal ArticleDOI
Generation of cylindrical vector beams of high orders using uniaxial crystals
TL;DR: In this article, the generation of cylindrical vector beams in birefringent crystals is studied analytically and experimentally in paraxial and non-paraxial regimes.
Journal ArticleDOI
Strengthening the longitudinal component of the sharply focused electric field by means of higher-order laser beams
TL;DR: This work has validated the growth of the longitudinal component in the focus for high-order modes at moderate NA=0.6-0.8, and essential lower sidelobes of Bessel modes, in comparison with LG modes.
Journal ArticleDOI
Experimental demonstration of the generation of the longitudinal E-field component on the optical axis with high-numerical-aperture binary axicons illuminated by linearly and circularly polarized beams
Svetlana N. Khonina,Sergey V. Karpeev,S. V. Alferov,Dmitry Savelyev,Janne Laukkanen,Jari Turunen +5 more
TL;DR: In this paper, the authors analytically and numerically show that by introducing asymmetry into axicon design, it is possible to generate the longitudinal E-field component on the optical axis for linearly and circularly polarized incident beams.
Journal ArticleDOI
Yeast-based self-organized hybrid bio-silica sol-gels for the design of biosensors
O. N. Ponamoreva,O. A. Kamanina,V. A. Alferov,A. V. Machulin,T. V. Rogova,V. A. Arlyapov,S. V. Alferov,N. E. Suzina,Elena P. Ivanova +8 more
TL;DR: The results demonstrated the influence of the MTES composition on the nature of the encapsulation of the yeast cells, together with the architecture of the three-dimensional sol-gel biomatrix that forms during the encapsulations process.
Journal ArticleDOI
Polarization converter for higher-order laser beams using a single binary diffractive optical element as beam splitter
TL;DR: A new approach to generating a pair of initial beams for a polarization converter that operates by summing up two opposite-sign circularly polarized beams is proposed.
