TLDR
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.
Abstract
Micron-sized particles have been accelerated and trapped in stable optical potential wells using only the force of radiation pressure from a continuous laser. It is hypothesized that similar accelerations and trapping are possible with atoms and molecules using laser light tuned to specific optical transitions. The implications for isotope separation and other applications of physical interest are discussed.

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.

Finer features for functional microdevices

TL;DR: Micromachines can be created with higher resolution using two-photon absorption, and the results can be higher resolution than previously reported using single photon absorption techniques.
