ADVANCES IN OPTICAL-FIBER-BASED LASER-INDUCED CAVITATION TECHNIQUES FOR SOFT MATERIAL CHARACTERIZATION

Abstract

This review explores the latest advancements in optical-fiber-based laser-induced cavitation techniques, emphasizing their applications in dynamic mechanical characterization of soft materials. The paper provides an overview of the principles of laser-induced cavitation, highlighting the role of optical fibers in delivering precise and controlled laser energy to induce cavitation within soft materials. Key advantages of this method over traditional mechanical testing techniques, such as minimal invasiveness, high spatial resolution, and the ability to probe localized material properties, are discussed. Recent technological developments, including innovations in fiber optics, laser systems, and cavitation detection methods, are presented alongside case studies that demonstrate the practical applications of these techniques in biomedical engineering, materials science, and tissue engineering. The review also addresses future prospects, potential challenges, and emerging trends in the field, offering a comprehensive understanding of how optical-fiber-based laser-induced cavitation can advance the characterization and application of soft materials.
