Lasers with average powers of several kilowatts have become an important tool for industrial applications. Temporal and spatial beam shaping was demonstrated to improve existing enable novel A very promising technology both highly dynamic power scaling is the coherent combining beams array high-power fundamental mode fibers. However, limited number fibers allows only resolution common phase front. It therefore favorable work plane or spherical fronts, which generate a “point”, i.e., diffraction pattern strong main lobe in focal plane. By applying tilt front, points can be positioned high resolution. The Civan DBL 6–14 kW investigated this switching between positions 80 MHz.
