我们通过数值证明，通过使用径向对称晶格，可以控制高功率自动聚焦波的焦斑特性和灯丝峰值强度。晶格诱导衍射能够隔离主轴上峰值并控制焦点位置。此外，在较高功率下，晶格可以控制并稳定长距离内灯丝的峰值强度。
We show numerically that by using radial symmetric lattices, the focal spot characteristics and filament peak intensity of high-power autofocusing waves can be controlled. The lattice induced diffraction is able to isolate the main on-axis peak and control the focus position. In addition, at higher power the lattice can control and stabilize the peak intensity of the filament over an extended distance.
