The transmission of electromagnetic waves (such as lasers) in plasma is a fundamental issue in plasma physics. In general, electromagnetic waves cannot be transmitted in high-density plasma, but their transmission and energy transfer play a crucial role in applications such as fast ignition laser fusion, laser particle acceleration, and ultra short and ultra bright radiation sources.In 1996, S. fr...
Winning the SEMA Best Engineering New Product Award is not an easy task. Therefore, it said a lot about Huali's new non floating fuel transmitter bringing hardware home. The Easy Level fuel level sender is a brand new design that does not rely on traditional float arm settings, but uses a frikken laser beam to measure the fuel level in the tank.More precisely, Easy Level uses LiDAR technology to m...
Recently, German laser giant Trumpf released data for the fiscal year 2023/24. The latest financial report shows that the group's sales decreased by 4% and order volume decreased by 10% in the fiscal year 2023/24.Despite these setbacks, Germany has become the company's strongest single market for the first time in many years, highlighting a shift in market dynamics.At the end of this fiscal year, ...
Researchers at the University of Bristol have made significant breakthroughs in expanding quantum technology by integrating the world's smallest quantum photodetector onto silicon chips. The paper "A Bi CMOS Electron Photon Integrated Circuit Quantum Photodetector" was published in Science Advances.In the 1960s, scientists and engineers were able to miniaturize transistors onto inexpensive microch...
IntroductionThe small hole mode swing laser welding has gained increasing recognition due to its ability to bridge gaps, refine microstructures, and enhance the mechanical properties of welds. However, the effects of amplitude, frequency, welding speed, laser beam power, and beam radius on heat flux distribution, melting mode, and three-dimensional temperature field have not been well understood. ...
