With reachable voxel sizes below the optical diffraction limit, it is of particular interest for biomedical or micro-optical applications. Despite its high resolution, the spreading of this method is hindered by its low productivity in the µm³/s range. Scaling up productivity is in principle possible with already available laser sources with high pulse energy and beam shaping such as multi-spot approaches. This beam shaping is limited in the processable volume and has to be expanded to arbitrary beam shapes in three dimensions to make use of the next generation laser sources with higher pulse energy and higher average laser power. In this work, a three-dimensional Iterative Fourier Transform Algorithm for optimizing arbitrary three-dimensional intensity distributions using a spatial phase modulator was investigated for suitability for 2PP.https://puma.ub.uni-stuttgart.de/bibtex/252038d698c243c6f0f700ccdf2f04f18/ifswifsw2024-05-08T09:44:08+02:00myown spatial-light-modulator three-dimensional-beam-shaping two-photon-polymerization Iterative-Fourier-Transform-Algorithm <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Alexander Peter" itemprop="url" href="/person/1ca633dd302c4f8c5615eaddda0ddce46/author/0"><span itemprop="name">A.
