项目摘要
The force sensing, optomechanics, and variety of quantum motion experiments require accurate and precise measurements of the acting forces. Using the momentum of absorbed and re-emitted photons of the laser field it is possible to generate calibration forces directly traceable to the International System of Units (SI). In this project we propose a method of extending the effective use of the momentum of the photon by utilization of the power of the multi-pass laser beam. We provide a comparison of the basic theoretical computations with the confirming initial experimental measurements focusing on a particular example of geometrical and experimental settings by which the augmentation of the forces produced by the momentum of the photon is extended from several hundreds of pN up to sub-μN range. We aim to provide new perspectives, ideas and strategies of harnessing the quantum mechanics with the principles well defined in the classical mechanics. The objective is a systematic theoretical and experimental investigation of the possibilities to use quantum mechanical approach to generate forces and their measurements using classical mechanical systems. Also the opportunities to take into account the fundamental physical limits associated with this method and other competing contributing effects which in metrological tasks might be considered as error sources, to be investigated in details. Besides of the practical perspectives in applying this method in precision force calibration tasks, it is also proposed to use the method for calibration measurements of the power of the laser sources.
力感测、光学力学和各种量子运动实验都需要精确测量作用力。利用激光场的吸收和再发射光子的动量,可以生成直接可追溯到国际单位制(SI)的校准力。在本计画中,我们提出一种利用多程雷射光束的功率,来扩大光子动量的有效利用的方法。我们提供了一个基本的理论计算与确认的初始实验测量的比较,重点放在一个特定的几何和实验设置的例子,通过该设置,由光子的动量产生的力的增强从几百pN扩展到亚μN的范围。我们的目标是提供新的视角,思想和策略,利用量子力学与经典力学中定义的原则。目标是系统的理论和实验研究的可能性,使用量子力学的方法来产生力和他们的测量使用经典力学系统。还有机会考虑到与这种方法相关的基本物理限制和其他竞争性影响,这些影响在重复任务中可能被认为是误差源,有待详细研究。除了在精密力校准任务中应用该方法的实际前景外,还提出了将该方法用于激光源功率的校准测量。
