In a new publication from Opto-Electronic Advances, authors from the Laser Engineering Group in the School of Engineering at the University of Liverpool, Liverpool, United Kingdom, discuss two-photon ...

Photon upconversion through high harmonic generation, multiphoton absorption, Auger recombination and phonon scattering performs a vital role in energy conversion and renormalization. Excitons, the ...

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

Two-photon vision is a novel method with great potential for the future of ophthalmic diagnostics. Although it has many advantages, it requires improvement in key areas. International Centre for Eye ...

Two-photon microscopy is a type of fluorescence microscopy that, rather than exciting the sample with a single photon, makes use of multiple photons. The advantage over more traditional one-photon ...

Assistant Professor of Biomedical Engineering Yi Xue works on 2P-FOCUS, a new two-photon microscopy system, in her lab. The system promises novel insights into biological features that were once only ...

Scientists at ICTER, the International Centre for Translational Eye Research in Warsaw, Poland, have made a breakthrough and determined the luminance value for infrared radiation using photometric ...

Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity are ...
