论文摘要
我们通过实验证明了定制的完美Laguerre-gaussian（PLG）梁的产生，其强度最大值围绕任何所需的曲线定位。原理是在PLG梁的角光谱上作用适当的代数函数。我们表征了这些梁的传播特性，并将它们与具有相同强度曲线的非分类苛性束进行了比较。结果表明，自定义的PLG梁可以在传播过程中维持其曲线，而能量损失少于非划分苛性束，因此能够传播更长的距离。这种新结构梁将在光学通信，孤子路由和转向，光学扭转和诱捕，原子光学等领域具有潜在的应用。
We experimentally demonstrate the generation of customized perfect Laguerre-Gaussian (PLG) beams whose intensity maxima localized around any desired curves. The principle is to act appropriate algebraic functions on the angular spectra of PLG beams. We characterize the propagation properties of these beams and compare them with non-diffraction caustic beams possessing the same intensity profiles. The results manifest that the customized-PLG beams can maintain their profiles during propagation and suffer less energy loss than the non-diffraction caustic beams, and hence are able to propagate a longer distance. This new structure beam would have potential applications in areas such as optical communication, soliton routing and steering, optical tweezing and trapping, atom optics, etc.
