SpaceX and its billionaire CEO Elon Musk may finally have reason to look back in the satellite internet competition. On Thursday, Amazon revealed that it had successfully used a space laser technology called "Optical Intersatellite Link" to transmit connections between two Kuiper Program satellites in low Earth orbit, located 621 miles apart, at a speed of 100 gigabits per second. This is approxim...
Recently, the research team of the High Power Laser Element Technology and Engineering Department of the Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences, has made new progress in the study of improving the damage threshold of fused quartz elements through laser cleaning. The study proposes for the first time the use of microsecond pulse CO2 laser cleaning to enhance the dam...
Compared to Impressionist paintings taken 50 years ago, upon closer inspection of Impressionist paintings in museums, you may notice some strange things: some are losing their bright yellow hue.Taking the dramatic sunset in Edward Munch's masterpiece "The Scream" as an example. The once bright orange yellow parts of the sky have faded to off white.Similarly, in his painting "The Joy of Life", Henr...
Tools made of hard materials are very wear-resistant, but the tools used to produce these tools are prone to wear and tear. Laser tools are the solution. Researchers at the Fraunhofer Institute for Laser Technology (ILT) have developed a process chain that can use ultra short pulse (USP) lasers to shape and polish hard material components without the need to replace clamping devices.Drills, millin...
The fully 3D printed electric spray engine is suitable for small satellite in orbit maneuver, and its production cost is only a small part of that of traditional thrusters.Image source: Massachusetts Institute of Technology, USAThe Massachusetts Institute of Technology team recently demonstrated an electric spray engine made entirely of 3D printing technology, which can be propelled by emitting ...
