摘要

    摘要
  • 摘要: 为了减少多模光纤出射光场的散斑干扰，提出了把声光布拉格衍射效应所形成的不同衍射级耦合到多模光纤中，由于衍射级具有不同的偏振态，消弱了光场相干条件，进而在出射光场中消弱了散斑场的对比度，并通过对改变声场频率后得到的散斑场对比度的分析，证实了利用各向异性晶体TeO2能够控制散斑场对比度，改善出射场的高斯分布，得出了可以利用布拉格衍射效应减少散斑场干扰的可能性。
    Abstract: In order to reduce the speckle interference in the multimode fiber emission fields, we investigated whether the coupling of different diffraction grades derived from Bragg acoustooptic diffractive effect to multimode fiber could reduce the speckle field contrast. Through the analysis on the speckle field contrast subsequent to the changing of the sound field frequency, we demonstrated that the anisotropic crystal TeO2 could regulate the contrast of speckle field and improve Gaussian distribution. It is probable that Bragg diffractive effect could reduce the speckle field interference.
