Characterization and control of droplets optically trapped in air

摘要

In this contribution we present experiments used to control and characterize single optically trapped aerosol particles.These experiments include a counter-propagating optical tweezer, a feedback control mechanism to stabilize the particlein the trap and a two-angle optical scattering measurement to monitor the time-evolution of the particle size. Experimentalsetups and results are presented for these experiments.
