On March 14, 2000, Trumpf established its first company in China - Trumpf Metal Sheet Products Co., Ltd., headquartered in Taicang, 50 kilometers northwest of Shanghai. Nowadays, Taicang has become a global strategic stronghold for the company. 25 years ago, this production base was originally used to demonstrate sheet metal processing production for Chinese enterprises. In the seventh year after the success of this move, "Trumpf Machine Tool C...

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 Stability Using Green Laser Radiation" was publis...

In view of the reconstruction problem of stack imaging technology in noisy environment, Lin Nan's team from Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences, proposed an innovative method ProPtyNet based on unsupervised physical neural network, which is expected to be applied to chip CD measurement and defect detection. The article was published in Optics and lasers in engineering under the title of "Noise robust photograph...

Rocket Lab USA continues its path of vertical integration and has signed an exclusive but non binding agreement with MynaricAG, a German laser communication terminal (LCT) supplier and Rocket Lab supplier, to acquire the company for $75 million in cash or stock.If Mynaric achieves its revenue target, it will pay an additional revenue of up to $75 million. This acquisition depends on whether Mynaric can exit the Chapter 11 restructuring process ...

Recently, the research team of the High Power Laser Physics Joint Laboratory at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made significant progress in the study of single shot characterization technology for complex combination laser pulses. The research team utilized an improved broadband transient grating frequency resolved optical switch technology (TG-FROG) to achieve complete characterization of co...

The Chinese Academy of Sciences reduced the volume of the deep ultraviolet laser by 90% and achieved 193 nm vortex beam output for the first time. Professor Xuan Hongwen described "loading truck equipment into the car trunk". This technology enables a 30% reduction in the size of lithography features, breaking through the bottleneck of the 2-nanometer process. In the next three years, laser power will increase by a hundred times - when lasers are...

Recently, Eric Schmidt, former CEO of Google, will take over as CEO of Relativity Space, marking his first CEO position since leaving Google.Relativity Space is known for producing rockets using unusual technologies, including 3D printers, automated robots, and artificial intelligence. In 2023, Relativity Space successfully launched the Terran 1 rocket, proving that its 3D printing technology can operate effectively. When Schmidt joined Relativ...

The high-end laser cutting machine developed and produced by Dongying Lijin Zhancheng Laser Intelligent Manufacturing Company has become popular in overseas markets this spring. This equipment can not only use laser to quickly cut steel, but also freely swing on steel, "showing" beautiful pictures. The laser travels like a paintbrush flying, and the hard steel plate has been hollowed out into beautiful patterns with the flick of the smart arm's...

With the global transition of autonomous driving from L2 to L3+, in the battle between LiDAR and pure visual perception routes, LiDAR is redefining the industry landscape at an astonishing pace of technological evolution and quietly building a new industrial ecosystem in the era of intelligent travel. Before the end-to-end model of autonomous driving became mainstream, there were many discussions and controversies about the necessity of configu...

1. Research backgroundDirected energy deposition (DED), as an efficient and economical technology in the field of additive manufacturing (AM), is widely used in the manufacturing of metal materials. However, its high heating and cooling rates, as well as significant temperature gradients, often lead to rapid solidification, forming cross layer columnar grains and internal defects, seriously affecting the mechanical properties of additive manufact...

Recently, the Xi'an Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences has made significant progress in the field of intelligent spectral environmental perception. Relevant research results have been published in the top journal in the field of environmental science, Environmental Science&Technology (Nature Index, 5-Year IF: 11.7), and have been selected as cover papers. The first author of the paper is Liu Jiacheng, an...
