2024-01-12 Four-Beam Tiled-Aperture Coherent Beam Combining of High-Power Femtosecond Laser With Two Compressors doi:10.57760/sciencedb.14078 en Figure 1 shows the experiment setup. Figure 2 shows the spectrum distribution and re-compressed pulse duration of the four sub-beams. Figure 3 shows the phase differences and PSD for an open-loop and a closed-loop. Figure 4 shows the beam profiles in the focal plane of the four sub-beams and the four beams combined incoherently and coherently. Figure 5 shows the beam profiles in the focal plane when the phase lock point is not wellmatched to the focal spot.
