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 …

The Cr^ 3+-and Ti^ 3+-doped crystals of chrysoberyl (BeAl_2O_4) and beryllium
hexaaluminate (BeAl_6O_10) are very attractive for generation of near-IR ultrashort laser …

Coherent vector beams with involved states of polarization (SOP) are widespread in the
literature, having applications in laser processing, super-resolution imaging and particle …

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 …

An explicit formula for a type of beams, which in this work are called the “special” hyperbolic
Bessel-Gaussian (SHBG) beams, has been derived, using the method of the Hankel …

A concise method of deriving expressions for Gaussian-like solutions of the paraxial and
wave equation (ie 3 D d'Alembert equation) is presented. This method is based on the …

We demonstrate that the conical refraction of the input elegant Laguerre–Gaussian beams
can be effectively described through generalized Bessel–Gaussian light beams. We …

We report here the generation of a three-dimensional (3D) dark focus from a single focused
monochromatic Gaussian beam that undergoes conical refraction when it propagates along …

With an experimental set-up designed to record simultaneously the far-field and the near-
field patterns, we got lasing with feature of conical diffraction in the biaxial Nd 3+-doped KGd …

In conical refraction (CR), a focused Gaussian input beam passing through a biaxial crystal
and parallel to one of the optic axes is transformed into a pair of concentric bright rings split …
