Abstract

The two-photon polymerization (2PP) technique is a powerful tool for the fabrication of submicron resolution 3D microstructures. The high flexibility and relatively low costs allow to use this technique not only for 3D structuring but also for the forming of diffractive microrelief. Due to two-photon absorption, higher resolution than it could be possible with the well-known laser direct writing process can be achieved.
