Explores the principles of cavities and lasers, including Fabry-Perot resonators, Gaussian beams, cavity configurations, and absorption-emission-stimulated emission processes.
Explores gain saturation in laser systems and the dynamics of atoms in different energy levels, emphasizing the balance between pumping and emission processes.
Explores laser ablation, bending, and welding techniques, including the principles of laser ablation and the application of different types of lasers in materials processing.
