## Beschreibungstext

Twenty-One Semiconductors GmbH was founded in 2019 as a spin-off of the Institute of Semiconductor Optics and Functional Interfaces (IHFG) at the University of Stuttgart. The company produces and markets a completely new type of laser crystals that can be used to efficiently generate laser radiation in the visible spectral range.
The underlying MEXL technology enables laser manufacturers to realize a new generation of laser sources for biomedical applications to obtain more detailed information when analysing cell and tissue samples.
