TLDR
This novel design demonstrated high trapping efficiency and strong trapping robustness with a simple optical configuration, and offered a large free space for flexible integration with other measuring techniques, such as optical-trapping Raman spectroscopy, for on-line single particle characterization.Abstract:
We present an advanced optical-trapping method that is capable of trapping arbitrary shapes of transparent and absorbing particles in air. Two parabolic reflectors were used to reflect the inner and outer parts of a single hollow laser beam, respectively, to form two counter-propagating conical beams and bring them into a focal point for trapping. This novel design demonstrated high trapping efficiency and strong trapping robustness with a simple optical configuration. Instead of using expensive microscope objectives, the parabolic reflectors can not only achieved large numerical aperture (N.A.) focusing, but were also able to focus the beam far away from optical surfaces to minimize optics contamination. This design also offered a large free space for flexible integration with other measuring techniques, such as optical-trapping Raman spectroscopy, for on-line single particle characterization.read more

Trapping positions in a dual-beam optical trap
Aidan Rafferty,Thomas C. Preston +1 more
TL;DR: In this article, the effect of offsetting the beams in the direction of propagation and an imbalance in power between the two beams is considered for dual-beam optical traps, and the authors demonstrate that it is possible to fit the evolution of the particle trapping position in order to determine the position of a particle relative to the focal point of each beam.
