报告摘要：
利用由光强梯度和光动量产生的基本光学力，研制出了一种新型技术，在流体中给介电粒子提供一条灵活的路径。我们研制出光纤探针，将导引光束整形成类贝塞尔光束，实现独特的光学捕获/传输功能。在这次报告中，将具体讨论其基本原理、制备过程、最新实验结果，以及未来的应用前景。
Utilizing the fundamental optical attraction generated by light intensity gradient, and light momentum, a novel technique was developed to provide dielectric particles with a flexible route within a fluid. Fiber optic probe was developed to shape the guided beam into a Bessel-like beam to enable unique optical trapping/transport functionality. In this talk, basic principles, fabrication process, and most recent experimental demonstrations will be discussed along with future potentials.
