| 英文摘要 | Fiber-array beam director composed of numerous fiber collimators gives out excellent adaptive optics (AO) performance better than traditional AO-enhanced monolithic director owe to the extremely high bandwidth of the fiber-integrated phase modulator. For fiber laser transmission applications represented by coherent-beam-combining, correction of sub-aperture tip/tilts is needed to further promote the combined beam's quality besides the phase-locking control. For power reception of the incident laser beam, tip/tilts control is indispensable to ensure efficient and stable laser beam coupled from space into fiber. Here, we adopt adaptive fiber optics collimator as the tip/tilts device, which owns advantages of precise control, small inertia and convenience for packaging. While most existed tip/tilts control methods are restricted to optimization algorithms which suffer from disadvantages of low bandwidth utilization ratio. In this paper, research progress of tip/tilts control bandwidth promotion for beam combining applications in IOE, CAS is presented. Methods of inherent response delay compensation and active resonance suppression are proposed and experimentally validated. The experimental results give great prospects to future applications that utilize fiber-collimators-array as optical transceivers. © 2019 by SCITEPRESS - Science and Technology Publications, Lda.
