Abstract
• Analysis of accumulative 3D heating by laser pulses using Green's function method. • Accumulative heating under the pulse-periodic action of three types of heat sources. • Dynamics of residual temperature of titanium, monocrystalline silicon, dry bone. • Results useful for optimization of technological regimes of irradiation. In this paper, using analytical methods of the theory of thermal conductivity, the issue of accumulative 3D heating under multipulse laser irradiation of inorganic materials and biological tissues is studied. For a number of practically important cases, comparatively simple analytical dependences of the residual temperature on the number of laser pulses and their repetition rate have been obtained. The limits of their applicability are discussed. Examples of the application of the developed theory for specific cases of pulse-periodic laser irradiation of various materials, in particular, titanium, monocrystalline silicon, and bone tissue, are demonstrated.
