Fiber laser beam combining
WebAug 1, 2024 · Efficient laser beam combination provides an available approach to break through the power scaling limitations. With the extension of combined lasers and power enhancement of monolithic combinable fiber amplifier, the advantages of beam combining become more attractive. WebBeam Combining Linear fiber arrays are particularly suitable for spectral beam combining . For example, one may realize one fiber laser with each fiber of an array, and combine their beams with a diffraction grating, as shown in Figure 2. Figure 2: Spectral beam combining with fiber lasers.
