Optical trapping with continuous-wave lasers has been a fascinating field in the optical
manipulation. It has become a powerful tool for manipulating micrometer-sized objects, and …

Optical trapping and manipulation using structured laser beams now attract increasing
attention in many areas including biology, atomic science, and nanofabrication. Here we …

The principle of optical trapping is conventionally based on the interaction of optical fields
with linear-induced polarizations. However, the optical force originating from the nonlinear …

Propagations of coherent and partially coherent flat-topped beams through a focusing
optical system are formulated. The radiation force on a Rayleigh dielectric sphere induced …

We considered a generalization of the Laguerre–Gaussian (LG) laser beam family by using
a complex shift of the beam complex amplitude in Cartesian coordinates. In this case, LG …

The use of low-power high-repetition-rate ultrafast pulsed excitation in stable optical
trapping of dielectric nanoparticles has been demonstrated in the recent past; the high peak …

Optical trapping using laser tweezer has revolutionized the field of force spectroscopy
having enormous applications in biological manipulation. While a number of theories were …

Here we report how ultrafast pulsed illumination at low average power results in a stable
three-dimensional (3D) optical trap holding latex nanoparticles which is otherwise not …

We study an optical micromanipulation that comprises trapping, rotating, and transporting 5-
μm polystyrene microbeads in asymmetric Bessel-Gaussian (BG) laser beams. The beams …

We investigate the effects of pulse duration on optical trapping with high repetition rate
ultrashort pulsed lasers, through Lorentz-Mie theory, numerical simulation, and experiment …
