Two-photon absorption (TPA) is the simultaneous absorption of two-photons of the same or different wavelenth by a material. In physics two-photon absorption
TL;DR: This study explores the use of three-photon direct laser writing (DLW) to fabricate high-performance quantum dot (QD)-polymer filters, overcoming limitations of traditional two-photon processes. By utilizing a 1035 nm laser, the
Context: Continuous fabrication of high-aspect-ratio structures with nano/microscopic features is desirable for many applications in medicine and photonics, including custom-designed stents, micro-surgery equipment, and optical components. Two-Photon Continuous Flow Lithography: This paper
This post deals with the a new method for mulimaterials two-photon lithography from the paper entitled “Multimaterial 3D laser microprinting using an integrated microfluidic system” published in Science Advances[1] . Facile integration of
This video demonstration of two-photon lithography (laser direct writing) shows the fabrication of a microscopic castle on top a pencil lead. It was produced and shared by the team led by Prof.
Current techniques provide 3D printing of structures as small as few nanometers. Main candidates from producing complex 3D structures are two-photon lithography, ion-beam lithography and Atomic force microscopy based lithographic technique. The
This post will introduce a roll call of classic papers about direct laser writing (DLW) in a chornological order, and talk briefly about their significance. Over the years there have been many
Two-photon absorption (TPA) is the simultaneous absorption of two-photons of the same or different wavelenth by a material. In physics two-photon absorption is categorized as a third-order nonlinear optical phenomenon. The image on
