Meta-study of laser power calibrations ranging 20 orders of magnitude with traceability to the kilogram
Metrologia(2019)
摘要
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 (1e23 photons/s at a wavelength of 1070 nm). As a part of routine practices, we regularly perform internal (unpublished) comparisons between our various power meters to verify correct operation.
