Abstract

Laguerre-Gaussian (LG) laser modes (annular shaped modes with helical phase fronts) are used to both manipulate and cut microscopic particles. We use holographically produced LG laser modes to manipulate microscopic bubbles. Interference patterns formed from LG modes of opposite phase helicity are used to create three-dimensional structures and to continuously rotate glass rods. The technique of using and LG beam to create microscopic sections of chromosomes is described.
