A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not ...

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies.

When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

Scientists recreated one of the most important experiments in the history of physics—but this time, they used antimatter instead of regular matter. All matter particles have a corresponding antimatter ...

Do not exceed 10 mA of current! The electron diffraction tube is fragile. Handle with care. Turn down the high voltage when not in use. It is worthwhile to contrast the diffraction of electrons with ...

Researchers already knew the atoms in perovskites react favorably to light. Now they've seen precisely how the atoms move when the 2D materials are excited with light. Their study details the first ...

Using high-powered laser beams, researchers have simulated conditions inside a planet three times as large as Earth. The pressures achieved in this study, up to 1,314 gigapascals (GPa), allowed ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...
