摘要：

We report the first observation of the simultaneous three-dimensional confinement of both a low-index particle and a high-index particle within a single-beam optical trap by using a strongly focused laser beam containing an optical vortex. Experimental and theoretical investigations of the trap stability are described. (C) 1999 Optical Society of America [S0740-3224(99)00904-2] OCIS codes: 140.7010, 350.4990.
