From: Giant resonant light forces in microspherical photonics
Sequences of snapshots taken with 160 ms time intervals illustrating propelling of polystyrene spheres with different D: (a) 7 µm, (b) 10 µm and (c) 20 µm spheres. Laser light propagates from left to right. Inserts at the top of (a–c) schematically illustrate the type of sphere motion represented by the corresponding consecutive photos. Propelling of 7 µm spheres in (a) is very steady with vmax≈vav. Propelling of 10 µm sphere in (b) shows some variations of the particle velocity. Propelling of 20 µm spheres in (c) demonstrates giant instantaneous velocity between the third and fourth snapshots (counted from top down) reaching vmax≈0.45 mm s−1.
