Abstract
A primary standard force sensor and laser power meter are combined to achieve laser power traceability to Planck's constant by means of radiation pressure. We assess the statistical uncertainty for measurements of 1 kW, 2 kW, and 5 kW using an electrostatic force balance as the force sensor in our high amplification laser-pressure optic (HALO). Our initial findings over this laser power range show statistical variations of 0.16% to 0.28%, with lower noise achieved at the higher laser power. This is consistent with previous measurements using commercial force sensors requiring mass artifact calibration.Proceedings Title
