On-site multi-kilowatt laser power meter calibration using radiation pressure

We have demonstrated the calibration of a thermal power meter against a radiation-pressure power meter in the range of 20 kW in a manufacturing test environment. The results were compared to a traditional calorimeter-based laboratory calibration undertaken at the National Institute of Standards and Technology. The results are documented and the effects of non-ideal conditions typical of measurements in low-stability environments are discussed.
