Revolution in 3D laser nanoprinting

A recent article in Nature Photonics ( demonstrates that it is possible to replace two-photon absorption in 3D nanoprinting by two-step absorption. The use of small and cheap laser diodes instead of expensive femtosecond lasers has the potential of revolutionizing 3D printing as was also discussed in the corresponding „news & views“ section ( of the same issue. The paper is the result of a collaboration in the framework of the cluster of excellence 3DMM2O ( between the lab of Martin Wegener (KIT) and the CAM groups of Eva Blasco and Rasmus Schröder.
