傍轴光学中的基本Laser模:从计算机代数和模拟到实验观察

Fundamental Laser Modes in Paraxial Optics: From Computer Algebra and Simulations to Experimental Observation

Christoph Koutschan, Erwin Suazo, Sergei K. Suslov

摘要:

本文研究了非均匀傍轴波动方程的多参数线性和二次近似解,其中包括抛物波导中的振荡激光束,螺旋光束,以及弱变介质中其他重要的传播不变激光模式族。一个“智能”透镜的设计和类似的效果,超聚焦的粒子束在一个薄的单晶薄膜进行了讨论。在补充的电子材料中,我们提供了一个计算机代数验证的结果在这里,和一些相关的数学工具,没有证明的文献中。我们还演示了如何使用计算机代数来自动推导出一些公式,这是非常可取的,因为相应的手工计算是非常繁琐的。在数值模拟中,一些新的解决方案揭示了相当奇异的属性,值得进一步研究,包括实验观察。

英文摘要:

We study multi-parameter solutions of the inhomogeneous paraxial wave equation in a linear and quadratic approximation which include oscillating laser beams in a parabolic waveguide, spiral light beams, and other important families of propagation-invariant laser modes in weakly varying media. A "smart" lens design and a similar effect of superfocusing of particle beams in a thin monocrystal film are also discussed. In the supplementary electronic material, we provide a computer algebra verification of the results presented here, and of some related mathematical tools that were stated without proofs in the literature. We also demonstrate how computer algebra can be used to derive some of the presented formulas automatically, which is highly desirable as the corresponding hand calculations are very tedious. In numerical simulations, some of the new solutions reveal quite exotic properties which deserve further investigation including an experimental observation.
