Atoms in axially shifted tightly focused counter-propagating beams: the role of the Gouy and curvature phases
Koksal, K.; Lembessis, V. E.; Yuan, J.; Babiker, M. (Optıcal Soc Amer, 2020)We consider the interaction of atoms with two tightly focused and axially shifted counter-propagating optical beams. At sub-wavelength focusing, we find that the scattering force potential in the three-dimensional space ... -
Chirality and helicity of linearly-polarised Laguerre-Gaussian beams of small beam waists
Koksal, K.; Babiker, M.; Lembessis, V. E.; Yuan, J. (Elsevıer, 2021)The chirality and helicity of a linearly polarised Laguerre-Gaussian (LG) beam are examined. Such a type of light possesses a large longitudinal field amplitude when it is created with a sufficiently small beam waist and ... -
Chirality-enabled optical dipole potential energy for two-level atoms
Lembessis, V. E.; Koksal, K.; Yuan, J.; Babiker, M. (Amer Physıcal Soc, 2021)We consider the optical dipole potential energy, which arises from the interaction of a two-level atom with a circularly polarized Laguerre-Gaussian laser beam of small waist. The beam is characterized by the existence of ...
