论文摘要

随着对在高功率激光系统中使用轨道角动量(OAM)模式的兴趣越来越多,需要对焦点的高强度模式进行准确的数学描述才能实现。在这项工作中,我们得出了由高斯,超高斯和理想的高功率激光系统共同的高斯,超高斯和理想的平束产生的各种高强度轨道角动量焦点强度分布。然后,使用拟合的laguerre-gaussian函数将这些强度分布近似,作为描述理论和数值模型中高功率OAM光束的实用方法。

With increasing interest in using orbital angular momentum (OAM) modes in high-power laser systems, accurate mathematical descriptions of the high-intensity modes at focus are required for realistic modelling. In this work, we derive various high intensity orbital angular momentum focal spot intensity distributions generated by Gaussian, super-Gaussian, and ideal flat-top beams common to high-power laser systems. These intensity distributions are then approximated using fitted Laguerre-Gaussian basis functions as a practical way for describing high-power OAM beams in theoretical and numerical models.
