Abstract: A numerical simulation of the processing of diamond crystals when exposed to laser radiation with a wavelength of $532$ nm was performed. The calculation of the shape of the hole and temperature fields formed in diamond crystals as a result of laser heating was carried out using three modeling options: I — a three-dimensional analysis when exposed to laser radiation along a second-order symmetry axis ($L_2$), II — a three-dimensional analysis when exposed laser radiation along the axis of symmetry of the third order ($L_3$), III — three-dimensional analysis when exposed to laser radiation along the axis of symmetry of the fourth order ($L_4$). An experimental verification of the obtained results was carried out.

Keywords: laser treatment, diamond, finite element method.
