Summary on Grant Application Form |
|
The first aspect of this research program will develop techniques for generating a unique class of optical beam. These beams are termed optical bottle beams and comprise a zero intensity focus surrounded in all directions by regions of higher intensity. Such beams are of significant interest to scientific groups researching the optical trapping and manipulation of atoms.The second aspect of this research program is to use these bottle beams for the trapping of metallic particles within optical tweezers. Until recently, optical tweezers only worked for dielectric particles, ie those transparent to the laser light. Trapping micron-sized metal particles has only had limited success in 2-dimensinal trapping. Bottle beams will allow the technique to be extended to the 3-dimensional trapping of metal particles several microns in diameter, opening the possibility of optical tweezers being used for micro-fabrication within nano-technology.Although not central to the success of this project, it is intended to make holograms for the generation of optical bottle beams available to other research groups.
