Before a spectrometer can do any useful work, it needs to be calibrated to identify wavelengths correctly. This is usually done by detecting several characteristic peaks or dips in a well-known ...

If it is a galaxy, it would be the oldest known galaxy in the cosmos, but it could also be a brown dwarf or an early black ...

SuperLight Photonics has announced the SLP-2000, a compact full-spectrum SWIR supercontinuum laser that expands the company’s ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across ...

Since the Industrial Revolution, scientists estimate that the ocean has become around 30% more acidic from the uptake of ...

Abstract: In this letter, we propose and experimentally validate an improved method for high-precision locking of the laser center wavelength based on the absorption spectrum of saturated HCN gas, ...

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 ...

Absorption spectroscopy of a solution containing an analyte solute typically uses the transmission through a solvent as a reference based on the assumption that the solvent does not absorb light.

Abstract: Reconfigurable frequency selective rasorber (FSR) has garnered significant attention due to its in-band stealth ability for antennas. However, the robustness of stealth performance is ...

The UV-Vis spectrum is a graphical representation of light absorption. Wavelength (nm) is shown on the x-axis, representing the energy of absorbed light; absorbance or transmittance is plotted on the ...
