介绍了利用1 W连续波可见光（半导体）激光的辐射压力效应，在1 Hz左右的静态和动态范围内产生和标定微小精密力的实用方法。利用非重叠多次反射激光束锁定在准被动和/或主动宏观腔系统中引起的光子动量转移的叠加效应。有效激光功率（部分被实验捕获）被放大，使得光学产生的力从数百pN增加到亚μ N水平。本文提出的结果应被视为一种手段，用于扩展的边缘实际可验证的下限SI可追溯力计量。
Practical means of generation and calibration of the small precision forces in static and dynamic regimes around 1 Hz by the usage of radiation pressure effect from 1 W continuous wave visible (diode) laser light is presented. The additive effect of the transfer of photon momentum, caused by non-overlapping multiply reflecting laser beam locked within a quasi- passive and/or active macroscopic cavity system, is employed. The effective laser power (partially trapped experimentally) is amplified, such that the optically generated forces are increased from hundreds of pN to sub-mu N level. The results presented in this paper should be seen as a means for extending the edge of practically verifiable lower limits of SI-traceable force metrology.
