The unique combination of spectral flexibility and frequency precision that can be achieved in semiconductor disk lasers makes then an enabling tool in atomic physics and spectroscopy. Such precision tools are the building blocks on which future growth in key areas such as quantum technologies and sensing will be based.
Quantum technologies and sensing are priority topics at national and European level, and hence extremely fast moving. Strathclyde has played an important role in shaping research on semiconductor lasers for these applications and this studentship is designed to keep it at the forefront. Hence, working with key partners such as the National Quantum Technologies Hub for Sensors and Metrology (Prof. Kai Bongs), the Fraunhofer Centre for Applied Photonics (Dr John-Mark Hopkins), this project will seek to develop semiconductor disk lasers in a robust format and in a sub 5 litre form factor. This improvement in robustness and reduction in size have been identified by the National Quantum Technologies Hub as essential for the next generation of mobile optical clocks. If such clocks can be built, they will open up applications in, for example, gravitational surveying for civil engineering and satellite free navigation for submarines. These high impact, real-world applications have driven the significant governmental investment in quantum technologies.
