In this paper we demonstrate that spiral fields generate nondiffracting dark beams. A collimated laser beam incident on a compact disc, i.e., a commercial CD, was used as mask for the generation of spiral fields. We study theoretically and experimentally the intensity distribution near the axis of the optical system.
在本文中，我们证明了螺旋场会产生无衍射暗光束。将准直激光束入射到一张光盘（即商业CD）上，以此作为产生螺旋场的掩模。我们对光学系统轴附近的强度分布进行了理论和实验研究。
