Scientists have demonstrated that light alone can reversibly control magnetism in a topological material. Researchers at the University of Basel and ETH Zurich have found a way to flip the magnetic ...

By shining a focused laser beam onto a sample of material, a team at the Paul Scherrer Institute (PSI) and ETH Zürich showed ...

A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with ...

Chinese scientists have pushed solid-state vacuum ultraviolet laser technology to a new milestone by ...

Lasers are known for the monochromatic nature of their light, so much so that you might never have thought there could be such a thing as a white laser. But in the weird world of physics, a lot of ...

Students in the class ENGRI 1100: "Lasers and Photonics" engage in hands-on learning and build a laser for an assignment.

A single, ultrafast laser pulse has flipped the polarity of a ferromagnet without first heating it to the brink of losing its magnetism, pointing to a new way to write data at extreme speeds with far ...

Scientists have found a new method to convert fluctuating lasers into stable beams, defying classical laws of physics. This discovery has opened new opportunities to explore photonic technologies that ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...

Neutrino lasers: It’s an idea that many physicists didn’t see coming. At first glance, physics suggests that it would be impossible to make a laser of neutrinos, famously elusive subatomic particles.

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...
