Development of mathematical model of laser treatment heat processes using diffractive optical elements

Abstract

Calculation of laser beam intensity distribution in the focal plane of diffractive optical element was performed using software TracePro. To determine temperature fields occurring in the process of laser treatment of material, software of computational gas dynamics CFX version 15.0 and supercomputer "Sergey Korolev" were used. Temperature dependence of heat conductivity for the coating of the Ni-Al alloy produced by plasma spraying was determined. Alloy heat capacity was calculated based on additive rule. Besides, the temperature dependence of the absorption coefficient at CO 2 -laser treatment was also determined.
