Abstract: 
As a versatile tool for trapping and manipulating neutral particles, optical tweezers have been studied in a broad range of fields such as molecular biology, nanotechnology, and experimentally physics since Arthur Ashkin pioneered the field in the early 1970s. By levitating the “sensor” with a laser beam instead of adhering it to solid components, excellent environmental decoupling is achieved. Furthermore, unlike levitating particles in liquid or air, optical tweezers operating in vacuum are isolated from environmental thermal noise, thus eliminating the primary source of dissipation present for most inertial sensors. This attracted great attention in both fundamental and applied physics. In this paper we review the history and the basic concepts of optical tweezers in vacuum and provide an overall understanding of the field.

真空光镊技术综述

摘要:光镊技术自上世纪七十年代由阿瑟·阿什金开创以来,作为捕获和操纵中性粒子的通用工具,已在分子生物学、纳米技术和实验物理学等领域得到广泛研究和应用。基于光镊技术的传感与精密测量系统,通过激光束悬浮传感单元,而非与装置固连,相比传统固态传感器,无机械耗散。此外,与液体或空气介质中的光镊系统不同,在真空中运作的光镊系统可实现传感单元与环境的完全隔离。基于上述优势,基础物理学和应用物理学领域科学家对真空光镊开展了大量研究。本文回顾了真空光镊技术的基本概念和发展历史,帮助读者全面了解该领域。
