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
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
1. What is Two-Photon Direct Laser Writing (DLW)? Two-photon direct laser writing (DLW) is 3D printing for the microscopic world. This techniques goes beyond the smallest shapes and sizes that can be
