In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...

A series of laser flashes recently lit up the night sky above Mauna Kea in Hawaii. Experts say the lasers were emitted by a NASA spacecraft. When you purchase through links on our site, we may earn an ...

The properties of dense helium (He) — which happens to be a principal constituent of giant gas planets like Jupiter — at thermodynamic conditions between those of condensed matter and high-temperature ...

Scientists have ample evidence to prove the Earth is a sphere. But some social media users claim to have devised an experiment showing the earth is flat. The post shows a green laser beam projected ...

A nanophotonic mode-locked laser built on lithium niobate emits a beam of green laser light. Lasers have become relatively commonplace in everyday life, but they have many uses outside of providing ...

It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But that’s what happened in UMD’s Energy Research Facility, an unremarkable ...

Much raw material can be saved in the welding of high-performance electronics. This is the result of an investigation at the German Electron Synchrotron DESY of the Helmholtz Association in Hamburg.
