Optical trappings of ThO<SUB>2</SUB> and UO<SUB>2</SUB> particles have been first demonstrated in water using the radiation pressure of a TEM<SUB>00</SUB>-mode He-Ne laser beam of λ=633nm. It was observed that a ThO<SUB>2</SUB> particle was success- fully trapped three-dimensionally in the focus region and transferred by moving the focus. On the other hand, for a UO<SUB>2</SUB> particle of which a refractive index and an extinction coefficient are relatively large in the visible region, only two-dimensional trapping was observed when the beam focus was located near the bottom of the particle. One of the main difficulties in the optical trapping of nuclear fuel particles is attributed to their relatively large absorption coefficients in the visible region. Computational studies on three-dimensional op- tical trapping performances of absorbing particles were, therefore, perfomed with a simulation code based on geometrical optics. The present calculation can well predict the experimental results on the optical trapping characteristics for ThO<SUB>2</SUB> and UO<SUB>2</SUB> particles.
