This presentation will serve as a progress report regarding the ongoing research project of stimulating the growth of graphene using carbon dioxide laser ablation of silicon carbide wafers. Thus far, we have focused on the gas pressure, the proportions of the three gases (helium, nitrogen, and carbon dioxide), the optical cavity setup, and the current density of the ionized gases within the laser system. These parameters are essential to the achievement of our goals and had to be dialed in precisely through theoretical research and experimentation. We have now successfully restored and optimized the laser, allowing for various power levels to be obtained and used for ablation. This report will focus on the theory behind laser optimization, the processes leading to this accomplishment, as well as the proceedings of the overall project.
