Laser Manipulation of Micro Untransmissive Particles in Water

The laser trapping of untransmissive particles are discussed in this paper. Photon can generate the momentum to the untransmissive particle by diffraction and reflection on the surface of the particles.

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