Characterization and Calibration of Four High Energy Laser Calorimeters.

Abstract

Four spherical heat sink calorimeters were built for monitoring laser power in the Navy High Energy Laser Program. An extensive study was made to characterize the transfer of energy from a 90 kW lamp to one of the calorimeters. This characterization was then used in the calibration of all four. The standard deviations of the data indicate the precision of the calorimeters is within 2%, with the probable error in the accuracy of the calibrations within 5%. Calibrations calculated from the physical properties of the materials used in the calorimeters are within 5%, indicating that this is also a valid method of calibration. Details on the character of the response of the calorimeters are given in the report, and operating instructions are included. Keywords: Laser calorimeter; High energy laser.
