laser beam trapping

基本解释

In chapter three, the trapping force of strong focused laser beam exerting to Mie particles and Rayleigh particles is calculated.
第二章介紹了激光捕獲技術的基本原理，闡述了光鑷捕獲和操控粒子的機制。
In chapter 4, laser cooling and trapping and applications of ultracold atoms are reviewed. The beam and atom interaction theory is analyzed.
第四章針對空心光束的應用，綜述了激光與原子相互作用的物理機制，分析了空心光束冷卻原子的機理以及研究動態。

But, when the doughnut laser beam is used as trapping light, relative index can be less than 1. The beam waist of focused laser beam has a virtual affection for the trapping force.
但是，在空心光束中可以實現對地折射率粒子的穩定捕獲，即粒子的相對折射率可以小於1。
