Researchers from Columbia University in New York reported the latest research on reverse laser sintering of metal powders. The related achievements were published in Scientific Reports under the title "Invested laser sintering of metal powder".The researchers demonstrated the ability of reverse laser sintering technology to manufacture metal powder parts. Researchers first deposit a layer of coppe...
The first all-Italian quantum cascade laser was born at the National Research Center in Pisa. The protagonists of this milestone are two researchers from the Nanoscience Institute, Lucia Sorba and Miriam Serena Vitiello, who together with their research team designed and developed this innovative device.In fact, quantum cascade lasers have unique potential for detecting gases and other molecules, ...
Although lasers are common in daily life, their applications go far beyond the scope of light shows and barcode reading. They play a crucial role in telecommunications, computer science, and research in biology, chemistry, and physics. In the latter field, lasers that can emit extremely short pulses are particularly useful, approximately one trillionth of a second or less.By operating these lasers...
High intensity and high repetition lasers rapidly and continuously emit powerful bursts of light, capable of emitting multiple times per second. Commercial fusion energy factories and advanced compact radiation sources are common examples of systems that rely on such laser systems. However, humans are a major limiting factor as their response time is insufficient to manage such rapid shooting syst...
Recently, the research team of the High Power Laser Physics Joint Laboratory at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made significant progress in the study of single shot characterization technology for complex combination laser pulses. The research team utilized an improved broadband transient grating frequency resolved optical switch technology (T...
