Recently, Professor Nie Mingming from the Key Laboratory of Fiber Optic Sensing and Communication at the School of Information and Communication Engineering, University of Electronic Science and Technology of China, in collaboration with the University of Colorado Boulder, published a research paper titled "Cross polarized stimulated Brillouin scattering empowered photonics" in the top internation...
Scientists at the Technical University of Munich have made significant progress in measuring the Earth's rotation with unprecedented accuracy. Now, the ring laser from the Wettzell Geodetic Observatory can be used to capture data at a quality level unmatched anywhere in the world. These measurements are crucial for determining the position of the Earth in space, assisting climate research, and imp...
Laserline will once again showcase its latest laser systems for joining and deposition welding at this year's Welding & Cutting show in Hall 5. This time the focus is on the world's first blue diode laser with an output power of 4 kW, which is said to have been developed for processing copper components.Its 445 nanometer wavelength is absorbed by copper and copper alloys, which is five t...
In a recent study published in the journal AIP Advances, researchers used molecular and elemental spectroscopy techniques such as laser induced breakdown spectroscopy (LIBS), Raman spectroscopy, and Fourier transform infrared (FT-IR) spectroscopy to characterize mines in ancient Egypt.In this study, researchers examined various gemstones that can be traced back to the era of the pharaohs. The team...
