Pulsed Laser Technologies - Advanced Techniques and Cutting-Edge Applications

Pulsed Laser Technologies - Advanced Techniques and Cutting-Edge Applications presents a comprehensive exploration of modern laser science, bridging fundamental principles, advanced generation techniques, and emerging applications. Pulsed lasers employ sophisticated methods such as Q-switching, gain-switching, chirped pulse amplification (CPA), and mode-locking to deliver ultrashort, high-energy light bursts with exceptional precision. These breakthroughs have revolutionized diverse fields, from micro-fabrication and biomedical imaging to optical communications and precision manufacturing. This book brings together recent advances in fibre and mid-infrared laser systems, with a special emphasis on material innovations and design strategies that enhance pulse control, efficiency, and stability. Topics include the theory and modelling of Q-switched CO lasers, the role of low-dimensional nanomaterials, including MXenes, as next-generation saturable absorbers (SAs), and the development of compact artificial absorbers using single-mode-multimode-single-mode (SMS) fiber structures. The dynamics of soliton sideband formation, nonlinear pulse shaping, and multimode interference are analysed in depth, linking physical mechanisms to real-world laser performance. Applications extend from industrial material processing to biomedical therapies and photonic manufacturing. Notable case studies include femtosecond-laser-inscribed fiber Bragg gratings for mid-infrared lasers, picosecond Nd:YAG lasers for scar remodeling, and multiphysics modeling of pulsed laser welding and ultrashort-pulse metal ablation. The book culminates with the use of Q-switched lasers in multibeam pulsed laser deposition for high-entropy alloy thin films and optical sensing enhancement. Richly illustrated and grounded in both experimental and theoretical perspectives, this volume serves as a vital reference for researchers, engineers, and graduate students in photonics, laser physics, and materials science.
