Abstract
Laser-assisted micro-machining (LAMM) has emerged as a transformative technology in precision manufacturing, enabling the creation of highly intricate micro-features on various materials. This paper provides a foundational overview of LAMM technology, exploring its fundamentals, methods, and applications. The construction of the LAMM temperature field is examined because it is crucial to improve its efficiency and cost-effectiveness. The study delves into the development of industrial femtosecond laser micromachining systems, explores fabrication techniques using LAMM, and discusses its role in the production of ceramics and semiconductors. Furthermore, it examines the capabilities of LAMM in creating 3D microstructures and explores the materials commonly used in laser micromachining. Overall, this paper gives valuable insights into the possible uses of laser-based micromachining technologies in various domains, such as the semiconductor industry, microfluidics, optics, etc. and emphasises the need for additional research to overcome its limitations and increase efficiency and cost-effectiveness.
