Abstract

A system has been developed for measuring 1.064 µm laser pulses of about 10-15 J. The overall uncertainty of the system has been evaluated and is less than ± 15%. The details of the measurement system, its documentation relative to the NBS absolute reference calorimeters, and the associated uncertainties of measurements are discussed. Several silicon avalanche and PIN photodiodes have been evaluated. Measurements have been performed utilizing cw lasers, and laser pulses of about 30 and 200 ns. These measurements have demonstrated the feasibility of characterizing transfer standards for these low level energies by means of cw laser measurements and acousto-optic modulators. Such a system is discussed. The results of these evaluations and work towards realizing well documented transfer standards are also discussed.
