Two-Photon Laser Micro-Nano Fabrication; Understanding from Single-Voxel Level

Abstract

For laser nanofabrication using two-photon photopolymerization a deep understanding of the nature of focal spots that are related to two-photon excitation is essential for achieving a high spatial resolution in three dimensions. Here we report the use of a technology we call ascending scan for characterizing the three-dimensional size and shape of single polymerization elements (voxels) and introduce several features of voxels that have not been fully noticed before. These findings are important for tailoring nanofeatures according to design.
