Abstract

We review our recent advances in two-photon induced photochemistry to fabricate three-dimensional micro-objects made in polymers, proteins and noble metals using Q-switched Nd:YAG microchip lasers. We have synthesized a new photoinitiator that is about 4 times more sensitive for two-photon polymerisation with sub-nanosecond pulses at 532 nm. We describe the improvement of our fabrication process and strategies to obtain solid microstructures that correspond to their models. We report on our progress to make silver microstructures by the photoreduction of silver nitrate with microchip lasers at 1064nm.
