【摘要】：Airy光束是一种特殊的无衍射光束,具有自恢复性及自弯曲性。根据衍射理论对聚焦后有限能量Airy光束的自恢复现象进行了研究,利用三角棱镜和圆形聚焦透镜组成的光学系统产生了Airy光束,所得到的Airy光束衰减较快。通过增加透镜对光束进行修正,并对修正前后Airy光束的光强分布的变化进行数值模拟和对比。结果表明,在一定传输距离内,有限能量Airy光束聚焦后自恢复光束随着传播距离的增大很快衰减。通过加入校正透镜可以抑制Airy光束的衰减。
[Abstract]:Airy beam is a special non-diffractive beam with self-recovery and self-bending.Based on the diffraction theory, the self-restoring phenomenon of the Airy beam with finite energy after focusing is studied. The Airy beam is produced by using the optical system composed of triangular prism and circular focusing lens, and the Airy beam decays rapidly.The light intensity distribution of Airy beam before and after correction was simulated and compared by adding lens.The results show that the self-recovery beam attenuates rapidly with the increase of propagation distance after a finite energy Airy beam is focused within a certain propagation distance.The attenuation of Airy beam can be restrained by adding correction lens.
