Recently, US military industry giant Lockheed Martin announced that it will significantly increase its additive manufacturing capabilities and expand its factory in Texas. The expansion project includes approximately 16000 square feet of dedicated space for 3D printing technology, and the addition of some of the largest large format multi laser printers in the space (it is worth noting that Lockhe...
Laser sources operating in the 1.2 μm band have some unique applications in photodynamic therapy, biomedical diagnostics, and oxygen sensing. In addition, they can be used as pump sources for mid-infrared optical parameter generation and visible light generation through frequency doubling.Laser generation in the 1.2 μm band has been achieved by different solid-state lasers, including semicon...
Researchers from Annamarai University in India and South Ural State University in Russia reported a comparative study of resistance spot welding and laser spot welding of ultra-high strength steel for automobiles. The related research was published in The International Journal of Lightweight Materials and Manufacturing under the title "A comparative study on resistance spot and laser beam spot wel...
Recently, a research team from the Astronomical Glaciology Laboratory under the RIKEN Nishina Center (RNC) of the Japanese Institute of Physics and Chemistry announced that they have developed a new laser based sampling system for studying the composition of glacier ice cores.The above image shows the discrete holes sampled 150mm from the shallow ice core of the Fuji Ice Dome in Japan (Southeast ...
The new architecture based on metamaterials provides a promising platform for constructing large-scale production and reprogrammable solutions that can perform computational tasks using light.The idea of simulating computers - a device that uses continuous variables instead of zero sum ones - may evoke outdated machinery, from mechanical watches to bomb sight devices used in World War II. But emer...
