Abstract
The present invention involves a multi-point laser trapping device in which laser light is irradiated on medium that includes micro-particles, and captures and arranges multiple micro-particles within said medium simultaneously; and is characterized by irradiating the aforementioned laser light from a single laser light source, and by arranging in that light route grating which forms on medium a diffraction pattern consisting of multiple point laser spots.
