Abstract

A single-beam optical trapping of microscopic particles and biological cells is demonstrated by using higher-order mode Nd : YAG laser beams at 1.064 μm for the first known time. A stronger trapping force by a TEM₀₁* beam than that by a TEM₀₀ beam was observed and 360° rotation of a trapped red blood cell with a TEM_0n beam was achieved.
