Pulsed Laser Technologies (Hardback)

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. It not only captures the current landscape of pulsed laser technology but also points toward its evolving frontiers in next-generation light–matter interaction research.
