Zhao Yun/Columbia Engineering Company provided an advanced schematic of a photonic integrated chip, which aims to convert high-frequency signals into low-frequency signals using all optical frequency division.Scientists have built a small all optical device with the lowest microwave noise ever recorded on integrated chips.In order to improve the performance of electronic devices used for global n...
The interaction between strong laser pulses and plasma mirrors has been a focus of recent physical research, as they generate interesting effects. Experiments have shown that these interactions can generate a nonlinear physical process called high-order harmonics, characterized by emitting extreme ultraviolet radiation and brief flashes of laser light.Researchers from the Czech Extreme Light Infra...
Due to the surge in the deployment of small satellites, the increasing congestion of data transmission has always been a persistent problem in the aerospace industry. The collaboration between the Communication and Navigation Research Institute of the German Aerospace Center and Tesat Spacecom GmbH and Co. KG TESAT provides a powerful solution. They successfully developed and tested OSIRIS4CubeSat...
BMW explained how to use WAAM (Arc Additive Manufacturing) starting from 2025 to manufacture lighter and stronger automotive components and reduce waste generation, in order to optimize the use of generative design tools.The demonstrated WAAM process uses aluminum wire raw materials directly deposited through laser welding heads, enabling automotive companies to manufacture lighter and more robust...
Researchers from the University of Aveiro in Portugal and the School of Engineering at Porto Institute of Technology (ISEP) in Portugal reported a study on the influence of laser beam intensity distribution on the geometric shape and process stability of lock holes under green laser radiation. The relevant paper titled "Influence of Laser Beam Intensity Distribution on Keyhole Geometry and Process...
