Two-photon polymerization (TPP) and direct laser writing (DLW) techniques utilise focused ultrashort laser pulses to induce highly localised photochemical reactions in photosensitive materials, ...
The research team proposed a method called aberration-converged annular lithography (ACAL) system, as schematic diagram shown in Figure 1. The Gaussian beam is converted into a collimated annular beam ...
(a) Schematic of the laser direct-writing system. (b) Vertical view of the cantilever of the SNOM tip. (c) Details of the pyramid tip structure and three-dimensional (3D) multiphysics model in the ...
