ABSTRACT:
A laser trapping apparatus for optically trapping an optional micro-particle from a group of micro-particles such as microorganisms suspended in a medium by a laser beam focused at a focal point of an optical converging system at the focal point, the apparatus comprising:
a parallel beam output device for outputting a plurality of laser beams around an optical axis in parallel with said optical axis, and an optical converging system having an objective lens for focusing the plurality of laser beams irradiated from the parallel beam output device to the focal point.
