Research output: Contribution to journalArticlepeer-review


In this work we present a method for generating ultra-intense Laguerre-Gauss laser beams, using 3D direct laser writing of spiral phase plasma mirrors. These single-use mirrors provide an economical and scalable solution for arbitrary spatial beam shaping at ultra-high laser intensities. The use of these plasma-based optical devices is demonstrated for the case of an orbital angular momentum of l=1, with incident laser intensity of 1017 W cm-2.
