Single-aperture passive coherent beam combining of fiber lasers based on diffractive optical element

We demonstrate a single-aperture coherent beam combination with eight fiber laser beamlets using a one-dimention diffractive optical element in an all-optical feedback loop. The maximum output power is 1.5 W with near diffraction-limited beam quality.
