Abstract

Precision measurement of photon pressure by various methods has been ongoing for over a century, but without a metrological comparison between optical power and mass or force standards. The work summarized herein describes metrological methods for use of radiation pressure forces to interconvert between mass, force and laser power. These experiments have the potential to allow the accurate measurement of laser from a calibrated mass or force and vice versa in a fashion traceable to the International System of Units (SI). New results show potential improvements in both small force and laser power measurement uncertainties using these methods.
