Brightness Enhancement with Raman Fibre Lasers

Both Raman fibre lasers (lasers based on stimulating molecules to emit photons at a given frequency shift from the pump laser) and Rare Earth fibre lasers (which use rare earth elements to emit light) work as fibre-based laser sources. Scientists have become interested in Raman fibre lasers because Rare Earth lasers have power limitations, due to the excess heat generated by the lasing process. Dr Yaakov Glick and his colleagues in the Applied Physics Division, at Soreq Nuclear Research Centre in Yavne, Israel, collaborating internationally with other groups, have worked to increase the power of Raman fibre lasers, while simultaneously enhancing their brightness.
