Abstract

Two-photon photopolymerization is used to create structures with sub-micron details or tiny particles by solidifying monomer liquid in pre-defined locations with focused laser beam. The process is time consuming, especially when high volumes are processed, because the building blocks are typically 200 nm in diameter. Possible way how to speed up the technique is to use multiple focal points created by dynamically generated hologram. Corrections of the focal spot shape and even distribution the laser beam intensity is described together with examples of structures created with this method.
