Optical pulse drives a movement of a microsphere

Optical pulses has the ability to move a micro-object and this allows physicists, chemists, and biologists to explore a range of fundamental phenomena. If laser manipulation is achieved in transparent solids, for example, a glass, the manipulated object can be driven to wherever on the smooth surface, which is expected to be applied to the fabrication of optical devices and microelectromechanical systems. Here we demonstrate a new technique of manipulating a microsphere by optical pulsed field.
