ABSTRACT:
A method and apparatus for manipulating particles (micro, nano, and pico) having one or more characteristics with an optical trap formed by modulating a laser beam with a Diffractive Optical Element (DOE). At least one characteristic of the material is selected; and a laser beam having a selected wavelength corresponding to the at least one selected characteristic of the material is generated. Values of the DOE are calculated corresponding to the at least one selected characteristic of the material. The beam and the DOE are modulated to produce a holographic optical trap having properties corresponding to the at least one selected characteristic; the trap is focused to a beam focus or selected spot size; and the beam focus is located near a particle location for trapping the particle therein.
