UV light wavelengths are measured in nanometres, with one nanometre equal to one billionth of a metre.Ultraviolet raysare shorter wavelengths than visible light, which is why we cannot see them when seen naked-eye. Ultraviolet rays are in the wavelength range from 10 to 400 nanometers (nm)....

Ultraviolet radiation is one section of the electromagnetic spectrum. The range of wavelengths for ultraviolet radiation are between 400 nm - 10 nm. Ultraviolet radiation is divided into subsections, which have different applications. Ultraviolet radiation at wavelengths below or around ...
Tunable output of ultraviolet laser radiation in the 210-250 nm range is achieved by varying the signal or pump laser radiation wavelength while maintaining other input parameters. The large amount of optical data obtained in this work will contribute to the generation of deep ultraviolet laser ...
confirmed by various research groups108using a chromosphere model from ref.109and the coronal model from refs.106,107. These independent calculations consistently agree with each other and have been validated by observations of atomic lines in the soft X-ray range110and extreme ultraviolet range105....
Ultraviolet astronomical spectrograph calibration with laser frequency combs from nanophotonic lithium niobate waveguides Here the authors demonstrate ultraviolet astronomical frequency combs, derived from the near-infrared domain via efficient harmonic generation in nanophotonic waveguides, to provide precision cal...
This type of indefinite permittivity has also been observed in graphite at ultraviolet frequencies [69]. Graphite is essentially the simplest of the van der Waals crystals. Each layer is in the form of a hexagonal network of carbon atoms, with weak van der Waals coupling between the layers. ...
Thorium-229 nuclei exhibit a uniquely low-energy nuclear transition within reach of state-of-the-art vacuum ultraviolet (VUV) laser light sources and have, therefore, been proposed for construction of a nuclear clock3,4. However, quantum-state-resolved spectroscopy of the 229mTh isomer to ...
