Abstract
Light amplification by stimulated emission of radiation (laser) is a coherent and monochromatic source of electromagnetic radiation that can propagate in a straight line and hence, finds diverse applications. High power lasers can perform various manufacturing operations or material processing. This contribution provides the principle of laser materials processing and an overview of the engineering application of laser material processing. The manufacturing processes covered have been broadly divided into four major categories; namely, laser assisted forming , joining, machining , and surface engineering. Followed by a brief introduction to different types of lasers and their general application, fundamentals of laser–matter interaction and classification of laser material processing have been provided. The scope and principle of an individual process is described followed by a detailed update of the literature, scientific issues, and technological innovations. The entire discussion primarily focuses on correlating the properties with processing parameters and microstructure and composition.
