High sensitivity, levitated microsphere apparatus for short-distance force measurements
Akio Kawasaki, Alexander Fieguth, Nadav Priel +3
A high sensitivity force sensor based on dielectric microspheres in vacuum, optically trapped by a single, upward-propagating laser beam, is described. Off-axis parabolic mirrors a…
Absolute pressure and gas species identification with an optically levitated rotor
Charles P. Blakemore, Denzal Martin, Alexander Fieguth +4
The authors describe a novel variety of spinning-rotor vacuum gauge in which the rotor is a m-diameter silica microsphere, optically levitated. A rotating elec…
Precision Mass and Density Measurement of Individual Optically Levitated Microspheres
Charles P. Blakemore, Alexander D. Rider, Sandip Roy +4
We report an mass measurement of approximately-m-diameter, optically levitated microspheres with an electrostatic co-levitation technique. The mas…
Three-dimensional force-field microscopy with optically levitated microspheres
Charles P. Blakemore, Alexander D. Rider, Sandip Roy +3
We report on the use of 4.7-m-diameter, optically levitated, charged microspheres to image the three-dimensional force field produced by charge distributions on an Au-coated, mi…
Single-beam dielectric-microsphere trapping with optical heterodyne detection
Alexander D. Rider, Charles P. Blakemore, Giorgio Gratta +1
A technique to levitate and measure the three-dimensional position of micrometer-sized dielectric spheres with heterodyne detection is presented. The two radial degrees of freedom…
