2610 構成材料の違いによるレーザトラッピンク研究(S44-1 マイクロ気泡・粒子,S44 マイクロ・ナノフルイディクス)  [in Japanese] 2610 Laser trapping on solid metal particles composed of different material  [in Japanese]

The laser trapping on metal solid particles are discussed in this paper. Photon can generate the momentum to the untransparent particle by diffraction and reflection on the surface of the particles. We tried laser trapping of untransparent particles using an attractive force caused by the diffraction and radiation force caused by reflection. The laser trapping system contains CW YAG laser, which has 1.064 micron in wave length and an optical microscope. 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. The particles were at first scattered in a droplet placed on a slide glass and a stage was used in order to move the slide glass.
