Two-photon technology, which relies on overlapping light beams, can be used for three-dimensional multilayer storage and promises capacities of up to 10 Tbyte on a DVD-size disk. Today's optical ...

In the lung tissue image shown here, THG (green) visualizes cells and other structures, SHG (red) visualizes collagen fibres, while two-photon excitation (blue) visualizes autofluorescence, mainly ...

It provides an extremely high precision of about 1.2 x 10-4 at a photon energy of around 18.6 keV. Compared to conventional spectrometers, it achieves a signal strength that is four to 22 times ...

Get Instant Summarized Text (Gist) A quantum-controlled few-photon two-photon absorption (fpTPA) technique enables optical nanoprinting with feature sizes down to 26 nm, surpassing the diffraction ...
