In the framework of the thermoelasticity theory, a comparative analysis of the temperature fields and fields of thermoelastic stresses arising in the plates of crystalline sapphire in the process of single-beam and two-beam controlled laser thermosplitting is carried out using round and crescent-shaped beams. It is shown that the use of crescent-shaped beams provides the formation of tensile stresses necessary for the stable realization of the laser thermosplitting process, with a significant reduction in the maximum temperatures in the samples compared with the use of round-shaped beams.
Keywords: : thermosplitting, modeling, finite element method, temperature, single crystal, sapphire, thermoelastic stresses.
