Abstract
The research focuses on the femtosecond laser ablation process, a sophisticated technique that integrates advanced engineering and quantum physics. COMSOL Multiphysics software is employed to simulate and visualize the multiphoton photoelectric effect, a quantum phenomenon involving the interaction of high-intensity and short laser pulses with matter. This process requires complex modeling of interactions at ultrafast timescales.
Experimental validation is conducted using the only femtosecond laser available at LAU, highlighting the exclusive access to state-of-the-art equipment. The integration of simulation and experimentation adds a significant layer of complexity, as variables such as laser pulse width, power, repetition rate and material properties must align to achieve accurate results.
The interdisciplinary nature of the work demands expertise in quantum mechanics, laser-material interactions, and simulation techniques. The challenges inherent in combining theoretical models with precise experimental measurements underscore the difficulty of this research, which seeks to advance understanding in both quantum phenomena and practical engineering applications.
