Modern laser technologies are considered key future technologies with a wide range of potential applications in engineering. This modern textbook provides an overview of the fundamentals of laser technology necessary for understanding laser material processing, laser radiation sources and the types of lasers important for laser material processing, laser beam properties and interaction processes between laser radiation and matter, typical material processing equipment as well as beam shaping and beam guiding elements, and all laser material processing methods (ablation, drilling, marking, stress-induced cutting, cutting, welding, soldering, hardening, generating, laser-assisted RP methods). The enclosed DVD contains videos on processes and fundamentals of the subject.
