The 16 laser channels right after the gain medium are folded vertically after the first interferometric combiner to yield 8 beams, which are then folded horizontally to form 4 beams by the second interferometric combiner. These 4 beams are then folded by the next pair to form a single output beam with Gaussian distribution. (Credit: Nir Davidson) |
