Researchers at ETH Zurich have developed a laser oscillator that produces the most powerful ultrashort laser pulses ever.

Caption An ultrashort spin wave (red) running through a nickel iron layer. Towards the center of the layer, the magnetic direction (blue arrows) swings only up and down in a sort of knot, while ...

A 100-watt ultrashort-wave transmitter could weigh less than 50 lbs., said Dr. Hutcheson, and its signal would be strong enough to reach from moon to earth, even without the advantage of a ...

Using a transient imaging technique, the researchers were able to measure how the light pattern changes over time when ...
