This glossary provides brief and clear explanations of key terms in laser technology. It helps users navigate the content on our website more quickly and gain a better understanding of technical terms from the fields of research, development and application. In doing so, it establishes a common foundation for anyone wishing to learn about laser technologies, processes, fields of technology and application sectors. At the same time, the glossary makes complex topics more accessible and helps to clarify the interrelationships – from the basic principles of lasers to their use in industrial and scientific applications.
What makes a laser: from wavelength, power and beam quality, through coherence and beam shaping, to safety, operating principles and the fundamental properties of laser light.
What lasers can do in manufacturing: from cutting, welding and drilling, through ablation, texturing and polishing, to additive manufacturing, coating and the targeted modification of material properties.
What defines laser technology today: from additive manufacturing, surface engineering and laser measurement technology, through photonics, EUV technology and optical design, to digitalisation, AI and quantum technology.
Where laser technology is making a difference: from the energy sector, automotive engineering and mobility, aerospace, microelectronics, medical technology and healthcare, to quantum technology and nuclear fusion.
