Laser Ablation: Excimer Lasers
This lecture covers the principles and applications of laser ablation, focusing on excimer lasers. Topics include the generation processes, laser light intensity, Q-switching, wavelength selection, and technical specifications. The lecture also discusses the interaction of excimer light pulses with materials, ablation plume formation, and materials suitable for laser ablation. Various applications such as microstepper technology, keratectomy, and laser machining of polymers are explored. Additionally, the lecture delves into ultrafast laser ablation, mode-locking regimes, and the influence of pulse duration on ablation quality.
