The laser trapping of untransmissive particles are discussed in this paper. Photon can generate the momentum tothe untransmissive particle by diffraction and reflection on the surface of the particles. We tried laser trapping ofuntransmissive particles using an attractive force caused by the diffraction and radiation force caused by reflection.The laser trapping system includes CW YAG laser, which has 1.064 μm in wave length and an optical microscope.The motions of particles were monitored by a CCD camera on the top of the microscope and recordedby PC connected to the CCD camera.
