Publications, 11 December 2023
We offer to your attention a preprint “Numerical results of thermal processes occurring in materials under the action of femtosecond laser pulses” P11-2023-52 issued by the JINR Publishing Department. The authors are Ilkizar Amirkhanov, Ibrokhim Sarkhadov, Zafar Tukhliev.
In recent years, lasers have been created that generate ultrashort light pulses. Currently, there is an increasing need to create and improve reliable physical models capable of describing various processes in matter. At the same time, computer modeling now occupies one of the main places in the study of such problems.
The paper proposes a modification of the thermal spike model based on a system of two coupled hyperbolic heat conduction equations for an electron gas and a crystal lattice for modelling thermal processes occurring in materials under the action of femtosecond laser pulses. The action of the laser in the electron gas is taken into account through the source function.
The study has been performed at the Meshcheryakov Laboratory of Information Technologies and submitted to the Journal of Surface Investigation. X-ray, Synchrotron and Neutron Techniques.
