The Landau-level laser is an exciting concept for an unusual radiation source. It could efficiently generate so-called terahertz waves, which can be used to penetrate materials, with possible ...

An international research team led by the Helmholtz-Zentrum Hereon has, for the first time, succeeded in visualizing and quantifying the complex airflow dynamics directly above the ocean surface in ...

A Dutch-German team of scientists has succeeded for the first time in controlling a chemical reaction via steering the motion of electrons with ultrashort laser pulses of a precisely controlled ...

This news release is available in German. They shed light on atomic and molecular processes: ultrashort laser pulses are required to study extremely fast quantum phenomena. For years, scientists have ...

Researchers have engineered a laser device smaller than a penny that they say could power everything from the LiDAR systems used in self-driving vehicles to gravitational wave detection, one of the ...

Most people are familiar with optical lasers through their experience with laser pointers. But what about a laser made from sound waves? What makes optical laser light different from a light bulb or ...

April 3 (UPI) --In a series of experiments, scientists at Northern Arizona University used a laser beam to propagate, trap and later access long-lived sound waves inside specially designed crystalline ...

The LIG based metasurface with a size of 5 × 5 cm 2 can be rapidly prepared in just 5 minutes under ambient atmosphere. The continuous modulation between wave transmission/shielding in an ultra-wide ...
