The main target of this work is to decrease the uncertainty of measurement of laser beam power by isoperibolic calorimeters. Measurement and calibration operating regimes of the isoperibolic calorimeter are investigated experimentally. Temperature transients during the heating and cooling of the calorimeter core are studied. The differences of transient parameters in measurement and calibration operating regimes of the calorimeter are described. Initial data for design of the calibration model of the isoperibolic calorimeter are determined. It is recommended to take into account the nonlinear thermal and physical characteristics of the core materials.
