摘要

平顶光束在各种应用中都有很高的需求，包括均匀表面处理，干涉激光加工，修复和皮肤治疗。在本实验中，我们优化了相位光栅的方向，将光束在傅里叶平面上空间分离为提取分量和残差分量，并对这些分量进行空间滤波，形成内部无波状结构、边缘陡度高的方形或六角形平顶光束。

Precision beam shaping by spatial frequency filtering

Flattop beams are in high demand for a variety of applications, including uniform surface treatment, interference laser processing, repairing and skin therapy. In this experiment, we optimized the direction of phase grating to spatially separate the beam into extracted and residual components in the Fourier plane, and spatially filtered the components to form a square or hexagonal flattop beam with no wave-like structure inside and high edge steepness.
