Lasers Induce Localized Cross-Linking Reactions in Non-Photosensitized Polymers
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 additive manufacturing. This research also widens the technology’s field of applications where the avoidance of a photo-initiator is preferable or is even a necessity, such as micro-optics, nano-photonics, and biomedicine.
