WebFeb 22, 2024 · Coherent beam combining (CBC) aims at increasing the spatial brightness of lasers. It consists in maintaining a constant phase relationship between different emitters, in order to combine them constructively in one single beam. We have investigated the CBC of an array of five individually-addressable high-power tapered laser diodes at λ … WebFeb 1, 2024 · The output power of the single-emitter semiconductor diode laser is always limited to a few watts [3]. A lot of laser beam combining methods, which can broadly be classed by either coherent or incoherent beam combining, have been provided to increase the single-mode power from single-emitter semiconductor lasers.
