Measurements with optically levitated microspheres
Abstract/Contents
- Abstract
- I discuss the development of optically levitated microspheres as a tool for precision measurements and tests of fundamental physics. Micron-scale dielectric spheres are trapped by the radiation pressure at the focus of a Gaussian laser beam, where the optical suspension enables thermal, electrical, and mechanical isolation from the surrounding environment at high vacuum. Forces and torques can be measured from changes in the angle and polarization of light both transmitted through and reflected by the trapped particle. Additionally, the charge of the particle can be controlled with single electron precision. We have used these methods for the following three purposes: to search for fractionally charged particles and dark energy, to develop measurement techniques for surface potentials, and to construct an electrically driven micro-gyroscope.
