Researchers in Australia report a novel approach to laser brightness scaling based on beam combination in a diamond Raman amplifier. Efficient power transfer to a Stokes input is demonstrated using a three pump beam arrangement. An analysis is also presented revealing that the concept may be applicable to continuous beam generation at kilowatt power levels and orders‐of‐magnitude higher when using isotopically purified diamond at reduced temperature.
