MIT team demonstrates pure quantum-mechanical mixture of electrons & photons in solid topological insulator bismuth selenide. To generate light-driven state, they used mid-IR light pulses that diverge & lose power rapidly as they propagate. Guiding pulses onto a sample in a vacuum chamber while maximizing their power required special optical setups developed in the lab. . #MIT #physics #photonics #materialsresearch #vacuumchamber
Nanoscribe’s Photonic Professional GT system uses a process known as two photon polymerization, in which a high-powered laser directs two photons of near-infrared (NIR) light in ultrashort pulses at photocurable resin. Combined with piezo-driven actuators and focusing optics, this allows for the 3D printing of objects with details finer than 200 nm.
