The tight focusing of laser radiation using 4-sector polarization converter
نویسندگان
چکیده
A laser beam with mixed linear-radial polarization formed by reflection of a linearly polarized light from a 4-sector micropolarizer was focused using a binary zone plate in a focal spot with diameters 0.35±0.02 and 0.38±0.02 of a wavelength.

Study of non-linear interaction of circular laser pulse propagating through hot magnetized plasma in the presence of a planar magnetostatic wiggler
In this paper, the self-focusing property of an intense circularly polarized laser pulse in hot magnetized plasma is investigated theoretically. First, an envelope equation governing the spot-size of the laser beam for both left- and right-hand polarizations has been derived in the presence of a planar wiggler. Furthermore, non-linear dispersion relation of laser pulse is obtained by using Maxw...
متن کاملThe Effect of Polarized Laser Radiation on Viscoelastic Properties of Soft Tissue
Background: Laser-tissue interaction on low-level laser therapy (LLLT) has widespread medical applications (e.g., improved wound healing). The tensile strength of radiated tissue by LLLT is known to be increased mainly because of cross collagen bands developed after radiation.Objective: In this work, we studied the instantaneous effect of radiation of polarized laser beam on the viscoelastic ti...

1. In existing projects of electron-positron colliders, the option of polarized electron and positron beams is considered [1,2]. While one can consider the problem of producing the polarized electron beams with required characteristics as having been solved [3], the existing approaches to polarized positrons generation [4-7] do not provide required parameters. In quoted papers the schemes were ...

A photonic crystal-based TE to TM polarization converter for integrated optical communication is proposed in this paper. The photonic crystal consists of air circular-holes in slab waveguide. The radius of holes are determined to be 291nm having lattice constant of 640nm using the gap map and band diagram. The polarization converter is composed of an InGaAsP triangular-shaped waveguide on SiO2 ...
متن کاملCharacterization of Nd: Yag Laser Radiation Effects on Ti6Al4V Physico-Chemical Properties: An In Vivo Study
The effect of a Nd: YAG laser (1064 nm) has been studied on Ti6Al4V alloy in terms of optical and physical parameters for biomedical applications. The superior surface microhardness hardness (i.e. 377 VHN) is attributed to grain refinement associated with laser melting and rapid solidification. The electrochemical property, mainly pitting corrosion resistance, has been carried out in Hanks salt...
