Lawrence Livermore National Laboratory develops PW grade thulium laser in the United States

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, Professor Xu Tingfa's research team from the School of Optoelectronics at Beijing Institute of Technology and Assistant Professor Lin Xing's team from Tsinghua University jointly developed a new type of Opto Intelligence Spectrometer (OIS). The device is based on diffractive neural network technology and achieves precise spectral reconstruction under spatially coherent or spatially incoh...

Recently, Laser Photonics (LPC) officially launched its SaberTech laser cutting system. This system not only enriches the product line of LPC's laser cleaning, welding, marking, and engraving systems, but also marks another important breakthrough for the company in the field of laser technology. This product release is another heavyweight measure after LPC's latest generation laser cleaning system...

Light can calculate functions during propagation and interaction with structured materials, with fast speed and low energy consumption. The use of all optical neural networks for general computing requires an optical activation layer with nonlinear dependence on the input. However, existing optical nonlinear materials either have slow speeds or very weak nonlinearity at the level of natural light ...

At last month’s LASER World of Photonics exhibition in Munich, Germany, industrial solutions and laser giant Trumpf presented a new materials processing laser system solution specified to improve welding processes.The system combines several sensors that monitor all process steps during laser welding. An integrated AI quality control system checks the weld seams, for example, and OCT (optical cohe...
