An open source three-mirror laser scanning holographic two-photon lithography system.

Summary Two-photon polymerization (TPP) is a leading technique for fabricating 2D and 3D nanostructures with sub-diffraction-limit features. This study introduces an open-hardware, open-software holographic multibeam TPP system featuring a phase-only spatial light modulator (SLM) and a three-mirror scan head. The novel three-reflective surface design—with two mirrors scanning along the same axis—resolves virtual conjugation loss in […]
