论文摘要
我们在低压下证明并表征了两个光学镊子之间悬浮二氧化硅纳米球的转移。两个光学陷阱都安装在光纤的头部，并放置在真空室的翻译阶段。我们的设置允许物理地将粒子加载环境与实验室分开，在该室中，第二个镊子可以将粒子放置在高技巧光腔内。分离阻止在颗粒载荷阶段破坏腔镜和腔室清洁度。我们的系统提供了一种非常可靠且简单的可再现方案，用于通过悬浮纳米颗粒制备腔体光学机械实验，为量子现象的系统研究开辟了道路，并减轻了传感设备的实现。
We demonstrate and characterize the transfer of a levitating silica nanosphere between two optical tweezers, at low pressure. Both optical traps are mounted on the heads of optical fibers and placed on translation stages in vacuum chambers. Our setup allows to physically separate the particle loading environment from the experimental chamber, where the second tweezer can position the particle inside a high Finesse optical cavity. The separation prevents from spoiling the cavity mirrors and the chamber cleanliness during the particle loading phase. Our system provides a very reliable and simply reproducible protocol for preparing cavity optomechanics experiments with levitating nanoparticles, opening the way to systematic studies of quantum phenomena and easing the realization of sensing devices.
