Laserline will once again showcase its latest laser systems for joining and deposition welding at this year's Welding & Cutting show in Hall 5. This time the focus is on the world's first blue diode laser with an output power of 4 kW, which is said to have been developed for processing copper components.Its 445 nanometer wavelength is absorbed by copper and copper alloys, which is five t...
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...
China's laser industry began in the 1980s, when the first private laser enterprise, Chutian Industrial Laser, was founded in 1985 by Sun Wen, an alumnus of Huazhong University of Science and Technology. In the 1990s, some young people with dreams began to make their mark in the laser industry. In 1995, Gao Yunfeng, 29, rented an apartment in Huaqiangbei with a deposit of 400,000 Hong Kong dollar...
Exploring the propagation and localization of waves in various media has always been a core focus of optics and acoustics. Specifically, in photonics and phononics, scientists have been dedicated to understanding and controlling the behavior of light and sound waves in periodic media.Photonic crystals have unique bandgap characteristics, providing an excellent platform for studying wave propagatio...
With funding from the National Science Foundation of the United States, researchers at the University of Rochester are developing photonic chips that use quantum technology called "weak value amplification" to replace mechanical gyroscopes used in drones, enabling them to fly in areas where GPS signals are obstructed or unavailable.Using this quantum technology, scientists aim to provide the same ...
