Paper Abstract

Calibration of a Coherent Radiation Model 213 laser power sensor is reviewed. The calibration chain is traced from the National Bureau of Standards (NBS) through transfer calibrations to a working sensor. Uncertainty components in this chain, including those for use conditions, are combined to give a root-sum-square uncertainty of 7% for use of this device.
