Absorption spectroscopy is an analytical chemistry tool that can determine if a particular substance is present in a sample by measuring the intensity of the light absorbed as a function of wavelength ...

A research group led by Dr. Toru Ube at Chuo University enabled 3D-selective deformation of “photomobile polymer materials” with the aid of two-photon absorption processes. Spatial selectivity of ...

Photon upconversion involves a series of non-linear optical processes where the sequential absorption of two or more photons leads to the emission of a single photon with energy greater than the sum ...

These applications put forward stringent fabrication requirements, including dimensional accuracy, shape accuracy, and surface roughness. Two-photon lithography is a versatile technique capable of ...
