Optical levitation

Optical manipulation was first demonstrated by the 2018 Physics prize Nobel laureate Arthur Ashkin when he 1971 at Bell Labs showed that glass beads can be levitated using a powerful continuous wave laser (App. Phys. Lett. 19 (1971) 283). His group later developed the single beam gradient trap also called the laser tweezers (Ashkin et al. Opt. Lett. 11 (1986) 288) which very soon became the standard tool in optical manipulation, mainly due its applicability in microbiology. In recent years a renewed interest in the technique of optical levitation has occurred, and we are currently involved in three different project using this method.
