摘要
The Mathieu beam is a typical nondiffracting beam characterized by its propagation invariance and self-reconstruction.These extraordinary properties have given rise to potentialities for applications such as optical communications,optical trapping,and material processing.However,the experimental generation of Mathieu–Gauss beams possessing high quality and compactness is still challenging.In this work,even and helical Mathieu phase plates with different orders m and ellipticity parameters q are fabricated by femtosecond laser two-photon polymerization.The experimentally generated nondiffracting beams are propagationinvariant in several hundred millimeters,which agree with numerical simulations.This work may promote the miniaturization of the application of nondiffracting beams in micronanooptics.
