Coherent beam combine
WebDec 1, 2024 · The two most common approaches for scaling the brightness of the diode laser source are wavelength beam combining (WBC) and coherent beam combining (CBC). In WBC, however, all beamlets are transformed into a single beam which spatially overlaps in both the near and the far field. WebMay 1, 2010 · Abstract. The designs of accelerator systems that will be needed to transform Fermilab's Project X [1-3] into a high-power proton driver for a muon collider and/or a neutrino factory are discussed. These applications require several megawatts of beam power delivered in tens or hundreds of short multi-GeV bunches per second, respectively.
