Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear ...

By integrating a holmium-doped ZBLAN photonic crystal fiber within a nonlinear optical loop mirror, the approach achieves high compression efficiency with minimal pedestal energy, offering a ...

Small, low-cost drones have rapidly expanded across military and public safety environments, creating what many now describe as an arms race between offensive UAS innovation and counter-UAS response.

Physicists have forced light to behave like electrons trapped in a magnetic field, producing a quantized sideways drift that had never been observed in photons before. The experiment, carried out on ...

Advances in artificial intelligence (AI) are now opening new possibilities for faster and more accurate flood mapping, enabling researchers to process large volumes of environmental data and satellite ...
