  title={Frequency Dependence of Temperature for Laser Marking on Bronze Samples CuAℓ 9 Mn 2}, 
  abstractNote={Temperature fields for laser marking of bronze samples CuAℓ 9 Mn 2 were obtained. Numerical experiments were conducted with the software program TEMPERATURFELD3D. The calculations refer to disc laser. For each numerical experiment we change the frequency and the power density. Graphs of the temperature dependence on the frequency for two power densities , were plotted. Preliminary work intervals for frequency are certain.},
