Lecture
This lecture introduces basic concepts in optics and light-matter interaction, covering absorption, refractive index, energy transfer with lasers, material response, and microtechnology applications. Examples include laser shot peening, 3D nanoprinting, cutting, joining, additive manufacturing, and laser eye surgery. It explores laser micromachining, weird phenomena like tilted structures and nanoparticle interactions, and the smallest lattice in the world. The lecture delves into quantum descriptions of photons, laser-matter interactions, and the essence of laser micromachining. It discusses the dynamics of energy transfer, the damped forced oscillator model, and the thermal transfer process. The lecture also touches on adaptive optics, femtosecond laser processing, and the potential of femtosecond lasers in creating engineered hydrophobic surfaces and self-organized nanostructures.
