Trapping and guiding microscopic particles with light-induced forces

Eckerskorn, Niko Oliver


Contact-free trapping and manipulation of light absorbing micrometer and nanometer-scale particles in air and in vacuum utilises radiation pressure, which results from momentum transfer from photons, and a pressure-dependent thermal force, caused by momentum transfer from gas molecules to the confined particles. Both forces are linearly proportional to the illuminating laser intensity, and both push the particles towards regions of lower intensity. While the...[Show more]
