Fig. 1: Experimental setup for attosecond-pump attosecond-probe spectroscopy. NIR pulses are focused behind a pulsed gas jet, where attosecond pulses are generated. At some distance from the gas jet, ...

Elemental spectroscopy is a method employed to examine in-service fluid samples such as engine oil or hydraulic fluid, to determine the presence and quantity of different substances. This approach ...

Researchers developed an optoacoustic (OA) terahertz spectroscopy system that can be used for long-term, non-invasive monitoring of blood sodium levels. Their approach successfully reduces signal ...

Spectroscopy, a branch of the physical sciences, investigates the interactions between electromagnetic radiation and matter. It involves analyzing how light interacts with a sample—whether through ...

Thermo Scientific ™ NanoDrop ™ Microvolume UV-Vis Spectrophotometers have been trusted in laboratories for over 20 years. With four models to choose from and software add-ons that enhance performance ...

A recent article in Advanced Photonics Research presents a mid-infrared dual-comb spectroscopy (DCS) system that eliminates the need for external photodetectors. The researchers developed a ...
