Turning red light into green - how does that work?

In second harmonic generation, the frequency of light is doubled in special materials, which changes its color. This method plays an important role in modern optics and photonics, including for laser technology and display applications.

A special highlight of the event is the insight into the inner workings of a green laser diode source. It illustrates how closely the theoretical principles are linked to practical implementation and makes the complex interrelationships understandable and tangible for all visitors. Come along and experience how scientific principles are directly translated into innovative technologies!
