The project aims to develop new imaging technology for real time recording of electrical activity from cell and neuronal networks with unprecedented resolution and scale. The technology innovation stems from an optical defect in diamond which can be engineered to sensitively detect local changes in electric field. The all-optical diamond optrode array devices will be applied to biological model systems including cardiomyocytes, mammalian cells, and neurons; and will be benchmarked against current state-of-the-art technologies. The knowledge gained from the high density recordings will aid predictive models of disease and will lead to an improved understanding of the brain’s micro circuity and functional connectome.Read moreRead less

We have recently made significant advances in development of all-solid-state intracavity Raman lasers generating multiwatt average powers in the near infrared and (by frequency doubling) visible spectrum, with important applications in biomedicine and remote sensing. A new generation of Raman crystals, especially tungstates, offer superior optical, mechanical and thermal properties, promising high Raman gains and choice of Stokes frequency shift.
