Vertical design improvement in high-power 780 nm pumps for high-energy class mid infra-red lasers
/forschung/forschungsnews/vertical-design-improvement-in-high-power-780-nm-pumps-for-high-energy-class-mid-infra-red-lasers
Efficient diode lasers at 780 nm are needed to pump thulium-doped solid-state lasers used in high-energy class applications. FBH scientists have recently improved the epitaxial layer structures…
In-line control of waveguide structures for non-linear optical processes
/forschung/forschungsnews/in-line-control-of-waveguide-structures-for-non-linear-optical-processes
Non-linear optical processes take place in waveguides with tiny cross sections and high index contrast. In order to achieve high efficiency, it is necessary to minimize optical losses. FBH has…
