High-Accuracy Laser Power and Energy Meter Calibration Service (NIST SP 250-62)
David J. Livigni
This document describes the high-accuracy laser power and energy meter calibration service provided by the National Institute of Standards and Technology (NIST). Calibrations are performed by dirct substitution of a test detector with a cryogenic laser radiometer, traceable to NIST electrical standards. The service currently supports measurements with laser powers from 0.1 to 1.0 mW, at several vacuum wavelengths in the range from 458 to 1550 nm. The expanded uncertainty (with a coverage factor of k = 2) of calibrations based on the primary standard typically ranges from 0.02 to 0.05 %. A detailed description of the measurement system and uncertainty analysis is presented.
