Abstract

Efficient and accurate modeling of coherent beam combining (CBC) was achieved using the scaled angular spectrum method (Sc-ASM) with graphic processing unit (GPU) acceleration. This approach simulates the propagation and combination of Gaussian beams while accounting for the spectral phase effects in ultrashort femtosecond pulses, including various orders of dispersion. Given the high costs of CBC systems, pre-experimental simulations are crucial. The integration of GPU acceleration significantly enhances the computational speed, making large-scale CBC system simulations feasible. This framework provides valuable insights into the experimental implementation and design of high-power laser systems.
