Polarization tailored novel vector beams based on conical refraction
A. Turpin, Yu. V. Loiko, A. Peinado +4
Coherent vector beams with involved states of polarization (SOP) are widespread in the literature, having applications in laser processing, super-resolution imaging and particle tr…
Super-Gaussian conical refraction beam
A. Turpin, Yu. V. Loiko, T. K. Kalkandkiev +2
We demonstrate the transformation of Gaussian input beams into super-Gaussian beams with a quasi flat-top transverse profile by means of the conical refraction phenomenon by adjust…
Type I and type II second harmonic generation of conically refracted beams
Alex Turpin, Yury V. Loiko, Todor K. Kalkandjiev +3
Type I and type II second harmonic generation (SHG) of a beam transformed by the conical refraction phenomenon are presented. We show that, for type I, the second harmonic intensit…
Wave-vector and polarization dependence of conical refraction
A. Turpin, Yu. V. Loiko, T. K. Kalkandjiev +2
We experimentally address the wave-vector and polarization dependence of the internal conical refraction phenomenon by demonstrating that an input light beam of elliptical transver…
Optical vault: reconfigurable bottle beam by conically refracted light
A. Turpin, V. Shvedov, C. Hnatovsy +3
We employ conical refraction of light in a biaxial crystal to create an optical bottle for trapping and manipulation of particles. We show that by just varying the polarization of…
Multiple rings formation in cascaded conical refraction
A. Turpin, Yu. V. Loiko. T. K. Kalkandjiev, J. Mompart
When a light beam passes through a cascade of biaxial crystals with aligned optic axes, the resulting transverse intensity pattern consists of multiple concentric rings. We provide…
