Abstract
We demonstrate a paradigm in absolute laser radiometry where a laser beam's power can be measured from its radiation pressure. Using an off-the-shelf high-accuracy mass scale and a 500 W Yb-doped fiber laser and a 92 kW CO2 laser, we show preliminary results of absolute optical power measurements with an accuracy of at least 7 %. We find a negligible contribution from radiometric forces. We also identify this scale's dynamic force noise floor (for a 0.1 Hz modulation frequency) as 4uN/Hz^1/2, or as optical power sensitivity, 600 W/Hz^1/2.Citation
