About the project

This project will investigate novel concepts for high power lasers operating in the visible and ultraviolet (UV) wavelength bands.

Scaling laser power in the visible and ultraviolet bands remains as one of the most significant challenges facing laser scientists, motivated by the needs of a growing number of applications in areas such laser processing of materials, medicine, sensing, defence and quantum technology. 

Traditional methods for accessing this wavelength regime are not compatible with operation at high power levels and so a different approach is needed. Our approach offers the prospect of unprecedented wavelength coverage across the entire visible and UV wavelength bands at very high-power levels and with high overall efficiency. 

The project will involve a detailed study into the physics of nonlinear frequency-converted fibre lasers operated at very high-power levels to formulate a strategy for power scaling and to determine the fundamental limits. The use of techniques, such as coherent beam combination, will also be explored for increasing power beyond the limit of a single source.
