Abstract

The laser trapping and manipulation by submillimeter size absorbing particles in the laser tweezer is investigated. The stable levitation of graphite, magnetite, tungsten carbide solid particles and its conglomerates was performed in laser trap formed by hollow laser beam focused by long-focal objective. The particles dynamics in the trap at normal and lowered air pressures was studied. The some new applications of laser tweezers with absorbing particles are discussed
