Andrés Fabián Lasagni, Denise Langheinrich and Teja Roch Fabrication of Circular Periodic Structures on Polymers Using High Pulse Energy Coherent Radiation and an Axicon Advanced Engineering Materials 14
In this study, we describe the fabrication of micrometer concentric ring structures on polymer substrate using an axicon and high power pulsed ultra violet laser radiation. The fabrication method consists on producing a periodic intensity distribution over the polymer's surface with a Bessel beam shape. This simple optical arrangement can be used to fabricate such periodic structures over several square millimetres.
