Tunable Bessel Beam in 2D PPLT Crystal

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate the generation of a tunable diffraction-free Bessel beam from a 2D periodically-poled LiTaO3 (PPLT) crystal. Our observation not only enriches the diffraction-free optics, but also has potential applications for photolithography and imaging.
