Attosecond lighthouse driven by sub-two
... using an a few-cycle infrared driver than are the beamlets produced with an 800 nm driver [15, 16]. Second, we show that long wavelength drivers allow us to apply the attosecond lighthouse to low ionization potential molecules. This opens a pathway for measuring important polar molecules where subse ...

V807 -Photon-Counting Avalanche Photodiodes – A Primer
... signals can be decomposed into a stream of “single” photons when viewed on a short time scale. Although the actual absorption of each individual photon is a random event that obeys Poisson’s distribution, a 1 W beam of 580 nm yellow light delivers one photon every 3.4×10-19 s on average. Of course, ...

Ultraviolet–visible spectroscopy
Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
