Abstract: We demonstrate a new principle of optical trapping and manipulation increasing more than 1000 times the manipulation distance by harnessing strong thermal forces while suppressing their stochastic nature with optical vortex beams. Our approach expands optical manipulation of particles into a gas media and provides a full control over trapped particles, including the optical transport and pinpoint positioning of $\ensuremath{\sim}100\text{ }\text{ }\ensuremath{\mu}\mathrm{m}$ objects over a meter-scale distance with $\ifmmode\pm\else\textpm\fi{}10\text{ }\text{ }\ensuremath{\mu}\mathrm{m}$ accuracy.

Tweezers with a twist
Miles J. Padgett,Richard Bowman +1 more
TL;DR: The fact that light carries both linear and angular momentum is well-known to physicists as discussed by the authors, and one application of the linear momentum of light is for optical tweezers, in which the refraction of a laser beam through a particle provides a reaction force that draws the particle towards the centre of the beam.

Optical pulling force
TL;DR: Theoretical analysis suggests that there exists an optical attractive force capable of "pulling" microparticles towards a light source as mentioned in this paper, which is generated by using interference to optimize the scattering of light in the forwards direction.

Observation of a single-beam gradient force optical trap for dielectric particles
TL;DR: Optical trapping of dielectric particles by a single-beam gradient force trap was demonstrated for the first reported time, confirming the concept of negative light pressure due to the gradient force.
Acceleration and trapping of particles by radiation pressure
TL;DR: In this paper, it is hypothesized that similar acceleration and trapping are possible with atoms and molecules using laser light tuned to specific optical transitions, and the implications for isotope separation and other applications of physical interest are discussed.
