高阶贝塞尔

1

Numerical calculations show that after focused by the axicon , a vortex beam can convert into a high-order Bessel beam .

数值模拟结果表明，涡旋光束经过轴棱锥聚焦后可获得高阶贝塞尔光束。

2

It is shown that there always exists an optical vortex at the center of the beams and the topological charge is conserved .

结果表明，高阶贝塞尔 -高斯脉冲光束经光阑衍射后，中心光涡旋始终存在，拓扑电荷守恒。
