Abstract

Two-photon induced 3D laser lithography is a widely used technique in additive manufacturing of three-dimensional micro- and nanostructures. However, efficient two-photon absorption (2PA) comes at a cost: It requires femtosecond pulsed laser sources leading to large and expensive setups. Recently, we introduced two-step absorption (2SA) as a novel alternative excitation mechanism[1]. This allows for employing low-power continuous-wave light sources like inexpensive, compact semiconductor laser diodes for excitation. Here, we present a compact setup based on 2SA drastically reduced in cost and size showing the potential in the field of 3D laser lithography. [1] Vincent Hahn, Tobias Messer, N.
