Tools made of hard materials are very wear-resistant, but the tools used to produce these tools are prone to wear and tear. Laser tools are the solution. Researchers at the Fraunhofer Institute for Laser Technology (ILT) have developed a process chain that can use ultra short pulse (USP) lasers to shape and polish hard material components without the need to replace clamping devices.Drills, millin...
Hybrid 3D integrated optical transceiver. (A, B) Test setup: Place the photon chip (PIC) on the circuit board (green), and glue the electronic chip (EIC) onto the top of the photon chip. (C) It is the cross-section of the EIC-PIC component with micro protrusions. (D) Display the mesh of the finite element model.The latest progress in artificial intelligence, more specifically, is the pressure plac...
With the increasing demand for human data, the requirements for data storage methods are also increasing. Optical Data Storage (ODS) is a light based storage method commonly used in DVDs, which is low-cost and very durable. But ODS usually stores data in a single layer, and the amount of data that can be stored is limited. Gu Min, academician of Shanghai University of Technology, Wen Jing, and Rua...
In industrial production, cleaning is a crucial step. Traditional cleaning methods, such as mechanical cleaning and chemical cleaning, although can meet production needs to a certain extent, often have problems such as low flexibility and environmental pollution. With the advancement of technology, laser cleaning technology has emerged as a new favorite in the cleaning field due to its high effici...
Recently, a team of Professor Ruan Shuangchen and Professor Zhou Cangtao from Shenzhen University of Technology proposed for the first time internationally a physical solution based on the generation of attosecond pulses and subperiodic coherent light shock radiation from a superluminal plasma wake field, and explained a new coherent radiation generation mechanism dominated by collective electron ...
