论文摘要
我们考虑通过分数fokker-Planck方程在高度向前尖锐的湍流介质中传播的光束建模及其通过分数费米铅笔梁模型的近似值。对于后一个模型，我们获得了一个误差估计值，这表明在小扩散极限中，费米铅笔梁的近似很好地捕获了光束扩展。
We consider the modeling of light beams propagating in highly forward-peaked turbulent media by fractional Fokker-Planck equations and their approximations by fractional Fermi pencil-beam models. We obtain an error estimate in a 1-Wasserstein distance for the latter model showing that beam spreading is well captured by the Fermi pencil-beam approximation in the small diffusion limit.
