Researchers at the Federal Institute of Technology in Lausanne have resolved the long-standing debate surrounding laser additive manufacturing processes through a groundbreaking defect detection method.The development of laser additive manufacturing is often hindered by unexpected defects. Traditional monitoring methods, such as thermal imaging and machine learning algorithms, have shown significa...
Recently, Associate Professor Li Jiawen's research group at the Micro and Nano Engineering Laboratory of the School of Engineering Science, University of Science and Technology of China proposed a femtosecond laser dynamic holographic processing method suitable for efficient construction of three-dimensional capillary scaffolds, which is used to generate a three-dimensional capillary network. This...
The laser driven particle accelerator on silicon chips was created by two independent research groups. With further improvements, this dielectric laser accelerator can be used in medicine and industry, and even in high-energy particle physics experiments.Accelerating electrons to high energy is usually accomplished over long distances in large and expensive facilities. For example, the electron ac...
On September 1 local time, Coherent, an American laser system solutions provider, announced that Dr. Mark Sobey, president of its laser division, has officially retired from the company.In July 2022, II-VI and Coherent completed the merger and were reorganized into three business units: Lasers, Materials and Networking. Since this point, Dr. Sobey has served as President of Coherent's Laser divisi...
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...
