Abstract
This paper presents the finite element modelling of the thermal field of a gemstone matrix by laser beam local heating. By using a continuous Gaussian beam of infrared laser a 3D temperature distribution in the gemstone material in the time domain is obtained. A tetrahedral mesh is used to solve the heat conduction equation in the entire 3D-structure. A transient thermal analysis of the interaction of the laser beam with the gemstone matrix reveals the temperature distribution profile throughout the volume of the material. The temperature profile of the computational model of the gemstone is in good agreement with the experimental observations.
