摘要	The output stability of coherent beam combining (CBC) is an important factor for its application in ultra-intense and ultra-short laser facility. Firstly, we combined theoretical simulations with experimental studies to improve the performance of four-beam tiled-aperture CBC system. By dispersion compensation, the pulse duration of the sub-beams was consistent, the combining efficiency was improved from 82.65 % to 89.80 %, 61.17 % to 68.44 % for two-beam and four-beam CBC system, respectively. Secondly, the beam combining scheme was optimized to improve the energy concentration of far-field focal spot. Meanwhile, numerical simulations show that our beam combining structure can achieve more than 90 % energy concentration in the large aperture PW lasers CBC system. Finally, to realize the long-term stable operation of CBC system, we optimized the feedback control algorithm. These results provide a pre-research analysis of the four-beam tiled-aperture CBC plan for the SEL-100 PW project. © 2024 Elsevier B.V.
