Modeling thermal energy transfer in copper undergoing femtosecond pulsed laser ablation using simple coupled pendulum
Abstract
Femtosecond pulsed laser ablation (fs PLA) is the process of emitting a pulsed laser beam onto a solid target to remove the material from the target surface. The aim of the study is to use a simple coupled pendulum system to create an analogous qualitative description of the energy transfer in the PLA based on the Two-Temperature Model (TTM). This study is divided into two cases (constant and mixed with angle-dependent parameters), where the parameters of the pendulum system are optimized to represent the thermophysical properties of copper. Results found that case 1 provides a better capability of representing the qualitative behavior of the TTM than case 2.
