Paper Abstract

3D laser lithography is a powerful technology to manufacture free-form micro- and nano-optical components. However, practical applications of these components are limited due to lack of knowledge of their optical resilience to intense femtosecond laser radiation, especially in the case of complex-shaped 3D structures. In this report, 3D woodpile structures were fabricated using 3D laser lithography in order to evaluate their laser-induced damage threshold (LIDT). For that S-on-1 testing method was performed on fabricated polymeric nanolatices showing their resilience to femtosecond radiation in the fluence range from tens to hundreds mJ/cm2. Furthermore, numerical modeling and experimental investigation were employed to deduce if the chosen geometry provided any photonic properties that could yield a change in the LIDT.
