Panasonic announced the launch of two new 1-Chip 4K DL laser projectors, the PT-REQ15 projector offering 15,000 lumens of brightness, while its counterpart, the PT-REZ15, offers 15,000 lumens of WUXGA resolution.The REQ15 uses Panasonic's Quad Pixel Drive, a two-axis pixel shift technology, to reproduce 4K images. It is capable of projecting 2K/240Hz content on multiple edge hybrid screens with a ...
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...
Coherent company's excimer lasers can be more widely used in fusion reactor applications, after the US based photonics giant signed a "letter of intent" with Japan's Faraday 1867 Holdings.Faraday 1867, headquartered in Kanagawa Prefecture, is said to have become the world's leading manufacturer of high-temperature superconducting (HTS) tape through its subsidiary Faraday Japan factory.This tape is...
Recently, a Japanese research team has developed a vertical deep ultraviolet emitting semiconductor laser device based on AlGaN, which is expected to be applied in laser processing, biotechnology, and medical fields.As is well known, ultraviolet (UV) is an electromagnetic wave with a wavelength range of 100 to 380nm. These wavelengths can be divided into three regions: UV-A (315-380 nm), UV-B (280...
A new study conducted by the US Department of Energy's SLAC National Accelerator Laboratory has revealed the strange behavior of gold when impacted by high-energy laser pulses.When certain materials are subjected to strong laser excitation, they will quickly disintegrate. But gold is exactly the opposite: it becomes more resilient and resilient. This is because the way gold atoms vibrate together ...
