英文摘要	focusing an annular laser beam can improve the axial trapping efficiency due to the reduction of the scattering force, which enables the use of a lower numerical aperture (na) objective lens with a long working distance to trap particles in deeper aqueous medium. in this paper, we present an axicon-to-axicon scheme for producing parallel annular beams with the advantages of higher efficiency compared with the obstructed beam approach. the validity of the scheme is verified by the observation of a stable trapping of silica microspheres with relatively low na microscope objective lenses (na = 0.6 and 0.45), and the axial trapping depth of 5 mm is demonstrated in experiment.
