The purpose of the bookmarks for the project Photonics4All is to increase the public awareness of photonics and especially of the technological advances of photonics which have changed and improved everyday life (basic technology introduction). Do you know how the metal pieces of your car have been welded? Nails and rivets are long gone! Today we use lasers to join multiple pieces of metal with different types of surfaces - curved or straight. Using lasers to cut and weld is cheaper, safer and faster than older techniques and lasers can be easily controlled by robots for high accuracy and high throughput. New powerful lasers can also be used to cut different materials such as plastics, ceramics and metals. The emergence of new types of lasers made it possible. All thanks to the progress in Photonics!
