论文摘要
这项工作介绍了带有冷冻波的微粒的第一个光学诱捕实验证明。冷冻波是一种有效的方法，可以通过以相同的频率和顺序为超级填充的贝塞尔束来纵向建模非划分光束的强度。使用空间光调节器的全息光学镊子进行了实验设置，已组装和优化。我们研究了作用在两种类型的冷冻波的微粒上的光学分布。结果表明，使用冷冻波可以获得更大的稳定性，以获得光学诱捕。从这种方法中捕获几何形状的显着增强表明，光学镊子，在广泛范围内的微型操作的有希望的应用。
This work presents the first optical trapping experimental demonstration of micro-particles with Frozen Waves. Frozen Waves are an efficient method to model longitudinally the intensity of non-diffracting beams obtained by superposing co-propagating Bessel beams with the same frequency and order. The experimental setup of a holographic optical tweezers using spatial light modulators has been assembled and optimized. We investigate the optical force distribution acting on micro-particles of two types of Frozen Waves.The results show that it is possible to obtain greater stability for optical trapping using Frozen Waves. The significant enhancement in trapping geometry from this approach shows promising applications for optical tweezers, micro-manipulations over a broad range.
