In the interaction between ultra short and ultra strong lasers and matter, short pulse width and high energy electrons are generated, commonly referred to as "hot electrons". The generation and transport of hot electrons is one of the important fundamental issues in high-energy density physics of lasers. Superhot electrons can excite ultrafast electromagnetic radiation in a wide range of wavelengt...
The most famous use of GPS satellites is to help people understand their location, whether it is driving cars, ships or planes, or hiking in remote areas. Another important but little-known use is to distribute information to other Earth observation satellites to help them accurately locate measurements of our planet.NASA and several other federal agencies, including the US Space Force, the US Spa...
Researchers at the National Institute of Information and Communication Technology in the United States have invented a new structure of a superconducting strip photon detector that can achieve efficient photon detection even in wide strips, and have successfully developed the world's first superconducting wide strip photon detector.The band width of the detector is more than 200 times that of trad...
This week, an illustration was published on the cover of the international journal Science, showcasing a powerful mode-locked laser emitted from a miniature photonic semiconductor.A research team led by Alireza Marandi, a professor of electrical engineering and applied physics at the California Institute of Technology, has successfully developed a conventional mode-locked laser large enough to fit...
Ultraviolet spectroscopy plays a crucial role in the study of electronic transitions in atoms and rovibronic transitions in molecules. These studies are crucial for the testing of fundamental physics, quantum electrodynamics theory, determination of fundamental constants, precision measurements, optical clocks, high-resolution spectroscopy supporting atmospheric chemistry and astrophysics, and str...
