(Nanowerk News) Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers (nm) in wavelength.

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...

Electromagnetic waves are members of a family of waves with common properties called the electromagnetic spectrum. The electromagnetic spectrum is a continuous range of wavelengths. The types of ...

Spectroscopy, in its broadest sense, is the term given to the investigation and measurement of spectra produced when a substance interacts with or emits electromagnetic radiation. All known matter ...
