Researchers from the University of Aveiro in Portugal and the School of Engineering at Porto Institute of Technology (ISEP) in Portugal reported a study on the influence of laser beam intensity distribution on the geometric shape and process stability of lock holes under green laser radiation. The relevant paper titled "Influence of Laser Beam Intensity Distribution on Keyhole Geometry and Process...
Recently, the research team of the State Key Laboratory of Intense Field Laser Physics of the Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics has made progress in the research on the nonlinear behavior and mechanism of platinum selenide in terahertz band. The research team systematically studied the spectral and optical intensity characteristics of platinum selenide und...
Just ten years ago, fiber laser cutting machines were considered experts in thin plates. The stores quickly realized that they had to invest in them to compete, at least by reducing their instrument materials. For high-quality sheet metal cutting, CO2 laser is still the way to go. Of course, fiber lasers can cut thicker blanks, but the quality is not very good, and their speed advantage almost dis...
They are the strongest lasers in history, and their beams are helping scientists explore the structure of the universe.In a research laboratory at the University of Michigan, bright green light fills the vacuum chamber of a technology giant. It is the size of two tennis courts. The walls are shielded with 60 centimeters of concrete to prevent radiation leakage, and workers wear masks and hairnets ...
Imagine being able to carry a 3D printer with you and quickly create low-cost objects, such as fastening bicycle wheels or parts needed for critical medical surgeries. Scientists from the Massachusetts Institute of Technology (MIT) and the University of Texas at Austin have combined silicon photonics and photochemical technology to successfully develop the first chip based 3D printer, taking a cru...
