Scientists and engineers at the University of Nottingham have measured the stiffness of space rock for the first time. Many meteorites are made of crystalline materials, formed under exotic conditions that cannot be replicated ...
In recent research published in Optics & Laser Technology and Infrared Physics & Technology, a research team led by Prof. Cheng Tingqing at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has introduced ...
Scientists have developed a dual-laser Brillouin optical correlation-domain reflectometry (BOCDR) system that uses two frequency-modulated lasers. By scanning the relative modulation phase between the pump and reference lasers, ...
Laser-cooled atomic gases, gases of atoms chilled to temperatures around absolute zero using laser technologies, have proved to be versatile physical platforms to study and control quantum phenomena. When these atomic gases ...
Communications with Mars explorers face unique challenges, including 4–24 minute signal delays and limited bandwidth that restricts data transmission. While NASA's Deep Space Network currently manages these communications, ...
Since last fall, NASA scientists have flown an advanced 3D Doppler wind lidar instrument across the United States to collect nearly 100 hours of data—including a flight through a hurricane. The goal? To demonstrate the unique ...
Laser-plasma accelerators can accelerate particles over distances that are up to 1,000 times shorter than those required by conventional accelerators. The technology promises compact systems that have enormous potential to ...
Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or frustrate your attempts at hanging holiday decorations. A beam of light doesn't sound like a material ...
Suddenly, there's a flash of intense light and heat, followed by a rapidly expanding fireball. Combustion of high explosives is everywhere in popular culture, and it's also critical for ensuring the safety and reliability ...
Laser plasma acceleration is a potentially disruptive technology: It could be used to build far more compact accelerators and open up new use cases in fundamental research, industry and health. However, on the path to real-world ...
