It was learned from the University of Science and Technology of China that the team of Professor Wu Dong of the Micro and Nano Engineering Laboratory of the school proposed a femtosecond laser two-in-one multi-material processing strategy, manufactured a micromechanical joint composed of temperature-sensitive hydrogel and metal nanoparticles, and then developed a multi-joint humanoid micromachine ...
Modern laser technology urgently requires nonlinear optical materials that can generate coherent light through second harmonic generation. However, only a small portion of the nonlinear optical properties of non centrosymmetric crystal materials have been experimentally or theoretically studied, and exploration for high-performance nonlinear optical crystal materials is still very limited.Recentl...
TRUMPF introduced its TruMatic 5000 manufacturing unit and new SheetMaster automatic loading and unloading device technology at the 2023 Blechexpo Metal Plate Processing Exhibition in Stuttgart, Germany.Users of the new system will benefit from fully automatic laser cutting, punching, and forming capabilities. The new SheetMaster device can achieve fully automated material flow within the manufact...
For example, the commonly used square shell battery cells for power batteries include laser welding of cover explosion-proof valves, laser welding of pole columns, and laser welding of cover plates and shells. During the process of laser welding of aluminum alloy, it is easy to generate unqualified phenomena such as explosion points, pores, welding cracks, excessive depth and width of fusion. ...
An international team of scientists is rethinking the fundamental principles of radiation physics, aiming to create ultra bright light sources. In a new study published in Nature Photonics, researchers from the Higher Institute of Technology in Lisbon, Portugal, the University of Rochester, the University of California, Los Angeles, and the Optical Applications Laboratory in France proposed the us...
