Two-photon absorption (2PA) is governed by different quantum-mechanical rules than one-photon absorption (1PA), and, as a result, the 2PA spectra are often much different in shape than their one ...

Two-Photon Absorption and Stimulated Emission in Poly-Crystalline Zinc Selenide with Femtosecond Laser Excitation In a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.210036 ...

Operando X-ray spectroscopy is a powerful tool for probing electrocatalyst dynamics—but intense X-ray exposure can distort structural insights. A recent article reveals flux- and dose-dependent ...

Quantum dots are microscopic semiconductor crystals developed in the lab that share many properties with atoms, including the ability to absorb or emit light, a technology that Los Alamos researchers ...

Right: typical optical spectrum of HÜBNER Photonics’ VALO Femtosecond Series lasers. (Courtesy: HÜBNER Photonics) “If you decrease the pulse duration by a factor of five, this gives roughly a five ...

Collecting X-ray absorption spectra during CT scans (via photon counting or spectral CT scanner) can provide more detailed information and contrast about what is going on inside the body, with ...

Spectra Absorption spectra. All elements either emit or absorb certain frequencies of light. Evidence from atomic line spectra supports the Bohr model of the atom using photon frequency calculations.

The highest resolution to date in a superconducting nanowire single-photon detector (SNSPD) camera has been claimed by researchers in the US. Designed by a team at the National Institute of Standards ...

They found that photon trapping led to a remarkable increase in the absorption efficiency over a wide band in the NIR spectrum, staying above 68 percent and peaking at 86 percent. Notably, the ...

This emitted photon is detected in AES and used to identify the element. Even the simplest element, hydrogen, has many possible electronic energy levels, ... In atomic spectra, absorption and emission ...
