A group of scientists created "slits" in time, allowing them to send light through the slits in a twist on an experiment first run over 200 years ago. In the original experiment, scientists sent light ...

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 ...

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 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 ...

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 ...

Quantum computing has long been constrained by the messy reality of controlling fragile qubits with bulky, power-hungry ...

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create ...

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

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 ...
