3-D laser damage positioned by deep-learning method

Traditional online damage detection schemes can directly detect and characterize damage by imaging optical components. However, due to optical resolution, noise, shadows and reflections, the small-size damage points cannot ...

High Altitude Water Cherenkov observatory tests speed of light

New measurements confirm, to the highest energies yet explored, that the laws of physics hold no matter where you are or how fast you're moving. Observations of record-breaking gamma rays prove the robustness of Lorentz Invariance—a ...

Physicists develop new photon source for tap-proof communication

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral ...

Scientists find a way to extract color from black

Scientists have developed a way of extracting a richer palette of colours from the available spectrum by harnessing disordered patterns inspired by nature that would typically be seen as black.

Researchers catch light in a funnel

Professor Ronny Thomale holds a chair for theoretical condensed matter physics, the TP1, at the Julius-Maximilian University of Würzburg. The discovery and theoretical description of new quantum states of matter is a prime ...

Scientists grow novel Er3+ doped LuSGG mid-infrared laser crystal

A study team has grown an Er3+-doped lutetium scandium gallium garnet crystal with high doping concentration. And this was the first time to grow that kind of crystal by Czochralski method. The team also announced they have ...

Researchers develop a black phosphorus all-fiber humidity sensor

A research group led by Prof. LI Jia and Prof. XU Xuefeng from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences, along with Prof. YANG Dexing from Northwestern Polytechnical University, ...

A device for the early detection of certain eyesight problems

EPFL researchers have developed a device that can zoom in on previously invisible cells at the back of the eye. The technology could be extremely useful for ophthalmologists, in particular for detecting age-related macular ...
