中文摘要:

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。

英文摘要:

Airy beam is a special non diffraction beam with self recovery and self bending.We studied the self recovery of the finite energy airy beam after focusing based on the diffraction theory. The airy beam generated by the optical system composed of triangular prism and circular focusing lens decays faster. We both found the beam can be corrected through adding the lens, and research on numeric simulation and comparation of the change of the light intensity distribution of the airy beam before and after the correction. The results show that the self restoring beam of the finite energy airy beam is attenuated rapidly with the propagation distance in a certain transmission distance. Therefore we concluded that the addition of the correction lens can suppress the attenuation of the airy beam.
