Laser in daily life and technology

The remarkable properties of laser radiation resulted in many technical applications. It is used in production technology, for measurements, spectroscopy and holography. Laser-shows are very popular but compliance with protection measures is mandatory.

Semiconductor lasers also known as laser diodes have important advantages. Therefore low power laser diodes are used in every day life, e.g. in laser pointers, laser printers, and CD/DVD players. Information technology takes advantage of the fact that laser radiation can be easily relayed in fibre optic cables.
