Meta-study of laser power calibrations ranging 20 orders of magnitude with traceability to the kilogram
Paul A. Williams, Matthew T. Spidell, Joshua A. Hadler +11
Laser power metrology at the National Institute of Standards and Technology (NIST) ranges 20 orders of magnitude from photon-counting (1000 photons/s) to 100 kW (10^23 photons/s at…

Micromachined force scale for optical power measurement by radiation pressure sensing
Ivan Ryger, Alexandra B. Artusio-Glimpse, Paul Williams +5
We introduce a micromachined force scale for laser power measurement by means of radiation pressure sensing. With this technique, the measured laser light is not absorbed and can b…

Measurement of differential polarizabilities at a mid-infrared wavelength in
C F A Baynham, E A Curtis, R M Godun +10
An atom exposed to an electric field will experience Stark shifts of its internal energy levels, proportional to their polarizabilities. In optical frequency metrology, the Stark s…
