The physics of optical vortices, also known as twisted light, is now a well-established and a
growing branch of optical physics with a number of important applications and significant …

In recent years, various methods have been developed to generate laser beams with zero
central intensity such as Laguerre-Gaussian beams, high-order Bessel-Gaussian beams …

With experimental realization of atomic Bose–Einstein condensation (BEC) and rapid
development of laser cooling and trapping techniques, all optical routes to quantum …

We report on the optimized production of a Bose–Einstein condensate of cesium atoms
using an optical trapping approach. Based on an improved trap loading and evaporation …

Trapping of neutral atoms has become possible in the last 15 years, thanks to the advances
in laser cooling techniques Adams and Riis, 1997). Several kinds of traps were developed …

A high-quality spectrally isolated hollow beam is produced through a nonlinear-optical
transformation of Ti: sapphire laser pulses in a higher order mode of a photonic-crystal fiber …

We present a simple method to convert a Gaussian laser beam into an annular beam using
a homeotropically oriented nematic liquid crystal. The method allows creation of a beam with …

In this thesis, I present the realization of a fiber-optical interface using optically trapped
cesium atoms, which is an efficient tool for coupling light and atoms. The basic principle of …

An optical microtrap is realized on a dielectric surface by crossing a tightly focused laser
beam with a horizontal evanescent-wave atom mirror. The nondissipative trap is loaded …

We explore theoretically how to tune the dynamics of a quasi-one-dimensional harmonically
trapped Bose-Einstein condensate (BEC) due to an additional red-and blue-detuned …
