Over the past 36 years much research has been carried out on Bessel beams (BBs) owing to
their peculiar properties, viz non-diffraction behavior, self-healing nature, possession of well …

Analytical formulas for the cross-spectral density matrix of a partially coherent radially
polarized Laguerre–Gaussian vortex (PCRPLGV) beam in anisotropic atmospheric …

Nonlinear wavefront shaping in periodically poled ferroelectric crystals has received great
attention because it offers a convenient way to generate a structured light beam at new …

We experimentally demonstrate stable trapping and controlled manipulation of silica
microspheres in a structured optical beam consisting of a dark focus surrounded by light in …

Optical tweezers enable noncontact trapping of microscale objects using light. It is not
known how tightly it is possible to three-dimensionally (3D) trap microparticles with a given …

Feedback control can be used to generate well-determined nonlinear effective potentials in
an optical trap, a goal whose applications may range from nonequilibrium thermodynamics …

We report on the development of a tunable spectral and spatial frequency shaping system
for ultrashort laser pulses using acousto-optic filters. The system enables the creation of …

We demonstrate a novel experimental scheme to generate and study the nonlinear
frequency conversion of a three-dimensional (3D) optical Bessel bottle beam (BBB). Using a …

We use path integrals to calculate perturbative corrections to the correlation function of a
particle under the action of nonlinear optical tweezers, both in the overdamped and …

We explore a degenerate four-wave mixing process induced by transversely structured light
beams in a rubidium vapor cell. In particular, we consider the nonlinear interaction driven by …
