论文摘要
在这项工作中，我们使用全息光学镊子将具有高阶冷冻波的光学捕获微粒。冷冻波是衍射光学束，通过以相同的频率和顺序使贝塞尔束进行超质磁，获得其形状的有效建模。基于此，我们开发了一种用于生成冷冻波的全息光学镊子系统，因此，可以以稳定的方式创建陷阱，以捕获和指导横向平面中的微粒。实验结果表明，可以使用高阶冷冻波获得光学诱捕的良好稳定性条件。这些结果表明，冷冻波对于光学捕获和指导颗粒有望有望在各种应用中使用，例如生物学研究，原子理和使用带有轨道角动量的结构光进行的光学操纵。
In this work, we optically trapping microparticles with higher order Frozen Wave using holographic optical tweezers. Frozen Waves are diffraction resistant optical beams, obtained by superposing copropagating Bessel beams with the same frequency and order, obtaining efficient modeling of its shape. Based on this, we developed a holographic optical tweezers system for the generation of Frozen Waves and with this, it was possible to create traps in a stable way for the trapping and guiding of the microparticles in the transverse plane. The experimental results show that it is possible to obtain excellent stability condition for optical trapping using higher order Frozen Waves. These results indicate that the Frozen Waves is promising for optical trapping and guiding of particles, which may be useful in various application such as biological research, atomic physics and optical manipulations using structured light with orbital angular momentum.
