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
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
