For a wide range of applications extending from photonics and metamaterials to lab-on-a-chip and tissue engineering, the construction of freeform two- and three-dimensional devices and structures with high resolution has grown more and more imperatively. To this end, lasers have proved to be an indispensable tool, as they can be focused and directed very accurately using conventional optics for flexible direct writing, and they can achieve sub-100 nm resolution, circumventing the diffraction limit by employing multi-photon processes.
The 23 papers published in this special issue cover the latest advances in the freeform fabrication of high-resolution, 2D and 3D structures using lasers, which include
