Structured light is derived from the ability to tailor light, usually referring to the spatial control
of its amplitude, phase, and polarization. Although a venerable topic that dates back to the …

This article reviews recent progress leading to the generation of optical vortex beams. After
introducing the basics of optical vortex beams and their promising applications, we …

The angular momentum of light can be described by positions on a higher-order Poincaré
sphere, where superpositions of spin and orbital angular momentum states give rise to laser …

This book deals with theoretical bases of the modern optics division concerned with
coherent light fields with singularities characterized by phase uncertainty. Singular light …

Structured light, with spatially varying phase or polarization distributions, has given rise to
many novel applications in fields ranging from optical communication to laser-based …

Light can be tailored to carry angular momentum well beyond the restriction of its two spin
states, left-and right-circularly polarized light, by imbuing it with orbital angular momentum …

We introduce a family of asymmetric Laguerre-Gaussian (aLG) laser beams. The beams
have been derived via a complex-valued shift of conventional LG beams in the Cartesian …

A simple method for generating a Laguerre–Gaussian (LG) mode optical vortex beam with
well-determined handedness in a single-frequency solid state laser end-pumped by a ring …

The unique properties of optical vortex beams, in particular their spiral wavefront, have
resulted in the emergence of a wide range of unique applications for this type of laser output …

We demonstrate an end-pumped Laguerre-Gaussian (LG) mode-selectable Nd: YVO_4
laser utilizing enhanced intracavity spherical aberration. The cavity was designed to exploit …
