High-quality femtosecond light sources are critical for developing advanced time- and angle-resolved photoemission spectroscopy (TrARPES), which is powerful in capturing the electronic dynamics in ...

Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

Can you briefly explain what transient absorption (TA) spectroscopy is and why it is important? Transient absorption (TA) spectroscopy is a pump-and-probe technique used to study the absorption of ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

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 ...
