Abstract:
We establish a theoretical multivariate-model of coherent polarization beam combination (CPBC) system including spectral-spatial phases to numerically analyze the multi-mismatch effect on the combining efficiency. After the comprehensive analysis of the typical system factors including the optical-path, spot-overlapping and beam-pointing deviations, the evolution of the combining efficiency with multiple misalignments is obtained. The characteristic of interaction among different factors is revealed, and the vectorial analysis is realized for the vector factors. Additionally, the occurrence and optimization of phase mismatch in spectral-spatial domains are investigated, and specific guidelines are given for a combination case. This model paves a way to do numerical analyzation of the temporal-spatial coherence of an optical-field, to assist current research of the coherent combination system and perhaps can be applied to other studies in the future.
