When running various artificial intelligence programs such as large language models, although data centers and high-performance computers are not limited by the computing power of their individual nodes, the amount of data transmitted between nodes is currently the root cause of the limitations on the performance and bandwidth transmission of these systems.Because some nodes in the system are more...
On September 1 local time, Coherent, an American laser system solutions provider, announced that Dr. Mark Sobey, president of its laser division, has officially retired from the company.In July 2022, II-VI and Coherent completed the merger and were reorganized into three business units: Lasers, Materials and Networking. Since this point, Dr. Sobey has served as President of Coherent's Laser divisi...
LiDAR sensors are crucial for implementing modern technologies such as autonomous driving, AR/VR, and advanced driving assistance systems. For example, more accurate shape detection in AR/VR devices and smartphones depends on the improved range resolution of medium and short range LiDAR. This requires a single photon detector with improved timing jitter performance.LiDAR calculates the distance an...
Snapmaker has been making three-in-one manufacturing tools -- The Snapmaker, Snapmaker 2 and Artisan -- for over six years now. These machines have changeable tool heads that can be used for 3D printing, laser cutting and CNC machining. At the beginning of this year, it branched out to make adedicated 3D printer, the J1-- a dual print-head machine that works very well -- and today the ...
Recently, the research team of the High Power Laser Element Technology and Engineering Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made new progress in evaluating the laser damage resistance and damage mechanism of 532nm thin film polarizers using different laser damage test protocols. The related achievements were published in Optical Materi...
