Laser Plasmas and Spectroscopy

Our research is focused on the interaction of intense lasers with matter, in all of its forms. Current applications include finding novel materials for next generation semiconductor manufacturing and laser based methods for contaminant analysis and removal from wind turbine blades.

About the Research Area

When an intense laser interacts with matter (in all of its forms), a set of complex optical and plasma processes are set in motion. By spectroscopically analysing the light emitted (or absorbed) during the interaction these processes can be understood, and even manipulated. A host of applications are enabled in areas as diverse as energy generation, manufacturing, novel materials and environmental monitoring. We collaborate widely with international laboratories and industrial partners on all aspects of the work from theory to experiment to translation.
