Lecture
This lecture covers the principles of two-photon absorption in 3D printing, explaining how materials can become absorptive at high optical powers, leading to pinpoint 3D resolution. It discusses the generation of laser power, typical setups for two-photon polymerization, and the fabrication time depending on scanning steps. The lecture also explores challenges in high-precision 3D printing, strategies to increase printing speed, and examples of bio-printing. Additionally, it delves into the fabrication of ultracompact multi-lens objectives, photonic wire bonding, and the process of 2-photon polymerization with glass. The lecture concludes with insights into micro glass prints, glass micro lenses, and the production of high-precision parts for replication.
