Combined system for optical cutting and multiple-beam optical trapping

In this article we describe a system which enables creation of several optical traps by splitting the laser beam in two parts and by using an acoustooptical deflector in one of these parts. This system is combined with a UV pulse laser so that a complex apparatus for optical trapping and cutting is obtained. Movable lenses ensure independent 3D positioning of a beam focus of the trapping and cutting beam without power losses at the back objective aperture. We present several applications of this system.
