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...
The ZEUS laser at the University of Michigan recently achieved a breakthrough of doubling the peak power of the strongest laser in the United States through its first 2 quadrillion watt experiment. Although this instantaneous power only lasts for 25 attosecond (one billionth of a second), it exceeds the total power of the global power grid by more than a hundred times.Karl Krushelnick, director of...
Researchers have made significant breakthroughs in controlling optical polarization, which is a key characteristic of various applications such as augmented reality, data storage, and encryption.This new method was developed by a group of scientists using liquid crystals to create holograms, which can manipulate the polarization of light at different points. This represents a significant advanceme...
It is reported that researchers from the University of Waterloo in Canada have reported a study on the plasticity of copper oxide nanowires induced by femtosecond laser. The related research was published in Applied Surface Science under the title "Femtosecond laser induced plasticity in CuO nanowires".Metal oxide nanowires are ideal materials for manufacturing nanodevices, especially strain senso...
The ocean covers over 71% of the Earth's surface, and so far humans have only explored about 5% of the ocean. This means that there are still 95% of the depths of the ocean that we know nothing about, making it the most mysterious and unknown place on our planet.600 years ago, Zheng He led a fleet to play the prelude to the era of great navigation, laying the foundation for us to understand the wo...
