Advancing Astronomy: Using Laser Guided Star Adaptive Optics to Obtain clearer celestial views

Archaeologists have long wondered why the people of Anglo Saxon England began using more silver coins and fewer gold coins between 660 and 750 AD. Researchers in Europe now say they have developed a method to help find the answer. This technology combines laser ablation with traditional trace element analysis to match the isotopic abundance of silver bars in coins with known sources of metal ores ...

At the UpakExpo 2024 exhibition to be held in Moscow at the end of January, Chinese company Golden Laser will showcase for the first time two laser die-cutting machines focused on the printing, labeling, and packaging markets in Russia.The Golden Laser LC350 is a web machine designed to handle labels printed on digital and flexographic printing machines. It can cut, die cut, and kiss cut paper, pl...

Mold cleaning: Mold plays a very important role in industrial production. Currently, there are over a thousand mold related enterprises in China, driving the related output value to nearly 10 billion yuan. Among them, mold cleaning is an essential step in mold production. Laser can achieve contactless cleaning of molds, which is very safe for the surface of the mold, ensuring its accuracy, and can...
