| Abstract: | Aiming at the problem of beam quality evaluation for external cavity-based spectral beam combining system with microlens array, the theoretical model for evaluating the beam quality of beam-combined laser is established. According to the model, the influences of relevant system parameters on beam quality are numerically analyzed in detail. The simulation results show that the beam quality is mainly influenced by the defocus value, the focal length of microlens and the mode field radius, while the influences... |
