Optical Trapping of an Ion [PDF]

open access: yesNature Photonics, 2010
For several decades, ions have been trapped by radio frequency (RF) and neutral particles by optical fields. We implement the experimental proof-of-principle for trapping an ion in an optical dipole trap. While loading, initialization and final detection

Optical-trapping micromanipulation using 780-nm diode lasers [PDF]

open access: yesPhysical Review A, 1993
We have designed and implemented an optical-trapping configuration that uses near-infrared laser diodes. The highly divergent output beam of the diode laser was collimated by using only one aspheric compact disc lens.

Magneto-optical Trapping of Cadmium [PDF]

open access: yesPhysical Review A, 2007
We report the laser-cooling and confinement of Cd atoms in a magneto-optical trap, and characterize the loading process from the background Cd vapor.

Modelling of optical traps for aerosols [PDF]

open access: yesJournal of the Optical Society of America B, 2010
Experimental observations suggest that there are differences between the behavior of particles optically trapped in air and trapped in a liquid phase.

Enhanced optical trapping [PDF]

open access: yesOptical Manipulation and Structured Materials Conference 2020, 2020
Optical tweezers have contributed substantially to the advancement of micro-manipulation. However, they do have restrictions, mainly the limited range of materials that yield to optical trapping. Here we propose a method of employing optically trapped objects to manipulate the surrounding fluid and thus particles freely diffusing within it.

Positioning Accuracy in Holographic Optical Traps

open access: yesMicromachines, 2021
Spatial light modulators (SLMs) have been widely used to achieve dynamic control of optical traps. Often, holographic optical tweezers have been presumed to provide nanometer or sub-nanometer positioning accuracy.

Artifact-free holographic light shaping through moving acousto-optic holograms

open access: yesScientific Reports, 2021
Holographic light modulation is the most efficient method to shape laser light into well-defined patterns and is therefore the means of choice for many intensity demanding applications.
