3. Multiphoton stereolithography

Single-photon stereolithography was the first additive manufacturing technology patented in 1984, using a polymerizable resin containing a photochemical initiator with layer-by-layer polymerization. . By being able to electronically excite an initiator with two photons, layer placement is avoided, making it easy to create nanometric but optically transparent objects, if desired.

3.1 General framework

Because we have long known how to "play" with the stigmatism...
