In 1832 Hamilton predicted that a collimated light beam propagating through a biaxial crystal
parallel to one of its optical axes refracts as a slanted cone within the crystal and emerges as …

Holographic recording and selective reconstruction and amplification of conical diffraction
vector waves are demonstrated using a nonlinear photorefractive S n _2 P _2 S _6 crystal …

In this paper, we extend the paraxial conical refraction model to the case of the partially
coherent light using the unified optical coherence theory. We demonstrate the …

We calculated the group velocity of light in internal conical refraction in a biaxial crystal as a
function of the direction of the electric displacement vector, or the vibration direction, of its …

Abstract A KGd (WO 4) 2 crystal has been used as the central piece of a prototype novel
optical sensor to identify the plane of polarization of a beam of light. The device identified the …

It is well-known that both the phase velocity surface and the ray velocity surface of a biaxial
crystal have two layers that touch each other at only four points. However, we show that the …

In this Letter, we study short-wavelength conical refraction (CR) via sum-frequency
generation (SFG) in the femtosecond regime, a previously unaddressed topic. Based on …

We theoretically prove that the group velocity of a light pulse traveling in an optic ray axis
direction of a biaxial crystal depends on the polarization state of the light. Our calculation …

In this paper, we extend the paraxial conical refraction model to the case of the partially
coherent light using the unified optical coherence theory. We demonstrate the …
