The University of Alberta creates a one-stop service center for advanced laser manufacturing

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...

Researchers at Rensselaer Institute of Technology have developed a device that operates at room temperature, which is the first topological quantum simulator to operate under strong light matter interaction mechanisms, making high-tech research easier in cutting-edge ways.Researchers at Rensselaer Institute of Technology have developed a device no larger than human hair, which will enable physicis...

Researchers from the Pacific Northwest National Laboratory and Johns Hopkins University have reported that machine learning and molecular dynamics simulations can help to gain a deeper understanding of the formation of condensation rings in laser spot welding. The related paper titled 'Machine learning and molecular dynamics simulations aided insights into conditioned ring formation in laser spot ...

Scientists at Purdue University in the United States have developed a new type of two-photon polymerization technology. This technology cleverly combines two lasers and utilizes 3D printing technology to print complex high-resolution 3D structures while reducing femtosecond laser power by 50%. It helps to reduce the cost of high-resolution 3D printing technology, thereby further expanding its appl...

In the interaction between ultra short and ultra strong laser and matter, electrons with short pulse width and high energy are generated, commonly referred to as "hot electrons". The generation and transport of hot electrons is one of the important fundamental issues in high-energy density physics of lasers. Superhot electrons can excite a wide range of ultrafast electromagnetic radiation, as well...
