In this proposal, the necessary research on the photon momentum setup with reproducible and SI traceable framework of quantum electrical-based measurements via Planck’s constant is described. The basis is a setup that integrates two State-of-the-Art measurement principles together, Kibble balance (i.e. Planck Balance – PB2) and photon momentum, using a special co nfiguration of the multi-reflected laser beam from ultra-high reflective mirrors for achieving a force amplification effect. Besides serving as a research platform that enables to investigate several fundamental metrological (measurement methodology) questions and raising the bar of State-of-the-Art measurement principles to the next level, it is constructed on individual component level based on conventional measurement methods and commonly available cost-effective materials allowing to obtain practical benefits, e.g. as a standard metrology setup highly demanded by metrology institutes globally, an industrial system for improved high precision and high accuracy small mass, small force and high energy laser optical power measurements and instrumentation calibrations, etc. Much attention deserves the operational (measurement) range that separates the quantum and classical mechanical measurement domains where only the use of macroscopic quantum electrical phenomena like the Josephson effect, and Quantum Hall effect allows to obtain the smallest possible reproducible and SI traceable measurement quantities with acceptable relative measurement uncertainties. Therefore, with this DFG project, an important contribution is being made for the creation of the scientific-technical foundations and implementation of the link between quantum and classical mechanics. Translated in terms of optical power and force values, arguably, this range stands at the several µW up to about 1 W level for power and 10 µN (mg) down to 10 pN (ng) for forces. Hence, the proposed work addresses not yet practically realized frontiers of small force (range: 10 µN to 10 nN), mass (1 mg to 1 µg), and optical power (mW to 100 W) measurements using fundamentally new State-of-the-Art methodology in a reproducible and SI traceable manner. And thus, the main research and development effort of the current proposal is aiming toward forthcoming complete measurement uncertainty estimations. The goal is to identify the relative measurement uncertainty of photon momentum generated forces below 100 nN and achieve estimated uncertainty for 10 µN – <0.001 (<0.1%), 1 µN – 1%.

在此提案中，描述了对光子动量设置的必要研究，并通过Planck常数可再现和可追溯的基于量子电气的测量值可再现和可追溯的框架。该基础是一种设置，该设置将两种最先进的测量原理集成在一起，即千利线平衡（即Planck Balance - PB2）和光子动量，并使用超高反射反射镜的多反射激光光束的特殊配置，以实现力量扩增效应。除了作为一个研究平台外，还可以研究几个基本的计量学（测量方法）问题，并将最先进的测量原理的标准提升到一个新的水平，它是基于传统的测量方法和常规可用的成本效益材料在单个组件级别上构建的，以获得实用的益处，例如。作为一种标准计量学设置，全球仪表机构高度要求，一种工业系统，用于提高高精度和高精度的工业系统小质量，小型和高能量激光器的光学功率测量和仪器校准等等。很多关注都值得关注的（测量）范围（测量）范围，可以将量子和经典的机械测量范围分开，而量子量只能分离出量子的速度和经典的机械效应，并具有麦克风效应的速度效应，并值得霍尔效应允许获得最小的可再现和SI可追溯测量量，并具有可接受的相对测量不确定性。因此，通过这个DFG项目，为创建科学技术基础和量子与经典机制之间的联系做出了重要贡献。可以说，以光功率和力值的形式翻译，该范围在功率的几个µW中，功率为约1 W级，而力量为10 µn（mg）至10 pn（ng）的力。因此，拟议的工作尚未实现尚未实现小力的前沿（范围：10 µn至10 nn），质量（1 mg至1 µg）和光电功率（MW至100 W）测量，该测量是使用基本的新型最先进的方法，以可重复的和可追溯的方式进行。因此，当前建议的主要研究和发展工作是旨在即将进行完全的测量不确定性估计。目标是确定光子动量产生的力的相对测量不确定性低于100 nn，并达到了10 µn - <0.001（<0.1％），1 µn - 1％的估计不确定性。
