Abstract
In this research, a Bessel tweezers system has been constructed successfully. One can demonstrate one of the remarkable properties of the Bessel beam—self reconstruction. Moreover, the Bessel tweezers system can also be used to guide micro-sized particles over 1mm, which is over 10 times the Rayleigh range. Furthermore, 5μm PMMA paticles are put in different dimensional cuvettes and the relationships between the guiding velocities and the dimensions of the cuvette are investigated. Finally, it is also found that the guiding velocities vary in a linear way with the laser input power which is below 300mW. This basic study is expected to provide the information and method to stimulate new research in the future.
