The analysis of test conditions of determining the thermal diffusivity of liquids by the laser pulse method are analyzed. Numerical solution of the nonstationary temperature pattern of three-layer sample when exposed to the surface of the thermal pulse of high power and low time span problem was found. The limits of the range of possible changes in the value of the heat transfer rate to the heating surface, corresponding to the conditions of reliable determination of the thermal diffusivity of a typical organic liquid ethanol without changing its phase state was determined.
