Dynamic beam shaping is of importance for a wide range of applications, such as light field regulation, laser processing, and advanced manufacturing. In this paper, an internal phase-sensing tiled-aperture coherent beam-combining system with seven beam elements was constructed for dynamic beam shaping. This system could be performed as a digital laser, where each laser beamlet functioned as an individual laser pixel. The amplitude and phase of each laser pixel could be adjusted independently in real time. In our experiment, the laser array was operated in three different configurations: the triangular, pentagonal, and hexagonal laser arrays, while each laser pixel was modulated with a different piston phase of nπ (where n was an integer). We demonstrated various beam-shaping patterns based on this system with output powers scaling over 1 kW. Additionally, the energy distribution of the emitted laser could be flexibly varied and customized. These results highlighted that our dynamic beam-shaped laser exhibited excellent performance in both dynamic beam-shaping and power-scaling capabilities. This work holds great potential for numerous applications involving beam shaping.
