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…
