A single, ultrafast laser pulse has flipped the polarity of a ferromagnet without first heating it to the brink of losing its ...

Scientists have demonstrated that light alone can reversibly control magnetism in a topological material. Researchers at the ...

Scientists enable excitons to surpass light to transform materials and open new advanced paths to quantum devices.

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

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 ...

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 ...

Researchers set a record by guiding light in 45-meter-long air wave-guides. It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But ...

In a discovery that could reshape how we view and understand the human brain, researchers have successfully passed a laser beam through an entire human head. While it may sound like science fiction, ...

An innovative experiment flying aboard NASA's Psyche mission just hit its first major milestone by successfully carrying out the most distant demonstration of laser communications. The tech demo could ...
