Solar-Blind Mobile Deep Ultraviolet Optical Communication Utilizing Photomultiplier Tubes

Photonics
Ozone in the atmosphere strongly absorbs deep ultraviolet light with wavelengths between 200 and 280 nm. Therefore, this characteristic is advantageous and promising for unperturbed, non-disturbed information transmission in fields such as secure ...

Deep-ultraviolet ptychographic pocket-scope (DART): mesoscale lensless molecular imaging with label-free spectroscopic contrast [PDF]

eLight
The mesoscale characterization of biological specimens has traditionally required compromises between resolution, field-of-view, depth-of-field, and molecular specificity, with most approaches relying on external labels.

Active volume scaling of gold vapor laser oscillating in ultraviolet and deep ultraviolet spectral ranges [PDF]

Scientific Reports
Using six laser tubes with various diameters, lengths, and volumes of the active zone, an investigation on an ultraviolet gold vapor laser is undertaken. We achieve a maximal average output power of 1.07 W at 312.2 nm wavelength.

Temperature-Dependent Self-Powered Solar-Blind Photodetector Based on Ag₂O/β-Ga₂O₃ Heterojunction

Nanomaterials, 2022
In this study, a high-photoresponsivity self-powered deep ultraviolet (DUV) photodetector based on an Ag2O/β-Ga2O3 heterojunction was fabricated by depositing a p-type Ag2O thin film onto an n-type β-Ga2O3 layer.
