Abstract

We present how to use the transfer of the momentum from the spatially periodic interference field to submicrometer-sized particles. The interference field is obtained by interference of co-propagating nondiffracting beams and counter-propagating nondiffracting and even evanescent fields. These types of trapping fields enable spatial organization of submicrometer-sized objects into one-dimensional arrays containing even thousands of objects, their controlled delivery over a distance of 1 mm, their sorting according to the size of refractive index. Moreover, the particle tracking enables to study the Brownian dynamics, jumps between neighboring optical traps and interactions between the objects. We present a group of new experiments studying particle behavior in such fields.
