Features of laser radiation with $1064$ nm, $532$ nm, and $266$ nm for the treatment of the crystals of diamond

Simulated diamond crystals processing by laser infrared, green and ultraviolet range was done. The analysis of temperature fields and thermal stress fields generated in the diamond crystals as a result of laser exposure was carried out for three different options: an analysis of the effect of laser radiation along the axis of symmetry of the second ($L_2$), third ($L_3$) and fourth-order ($L_4$).
