Paper Abstract

Quantum based devices offer distinct advantages over conventional technology, such as improved sensitivity for sensing applications or enhanced accuracy for metrology. To utilize this potential, a number of technical requirements must be met, such as the cooling and trapping of neutral atoms for their use as quantum systems. We present our work on InGaN-based semiconductor cooling lasers for a variety of atomic species such as strontium, magnesium and ytterbium whos target wavelength was met by quantum-well composition engineering. Results on growth-epitaxy, facet coating as well as different configurations such as ECDL and MOPAs are presented, depending on the requirement of the application.
