A research team has demonstrated that non-amplified #femtosecond #laser systems delivering 40–500 pJ individual pulses are sufficient for inducing localized cross-linking reactions within hundreds of nanometers in cross sections of non-photosensitized polymers. This experimental work is of high importance for the fundamental understanding of laser-enabled nanoscale 3D #AdditiveManufacturing.
