Holographic display technology provides the ultimate solution for true 3D display, with enormous potential in augmented reality and virtual reality. However, the color and viewing angle of holographic 3D displays mainly depend on the wavelength of the laser and the pixel size of the current spatial light modulator. The inevitable color difference and narrow viewing angle in conventional systems se...
Researchers from the University of Calabria, University of Salento, and LUM University in Italy have reported on the progress of finite element prediction research on laser surface treatment of Ti6Al4V alloy: melt pool morphology and microstructure evolution. The related research was published in The International Journal of Advanced Manufacturing Technology under the title "Laser surface treatmen...
A team of scientists at the Technical University of Denmark has created a selene-based solar cell by replacing thermal annealing with a new laser annealing strategy."In our work, we investigated the potential of this laser annealing strategy specifically for selenium thin film solar cells, and we report a new world record for fill factor, a new world record for ideal factor, and the most advanced ...
Recently, Eric Schmidt, former CEO of Google, will take over as CEO of Relativity Space, marking his first CEO position since leaving Google.Relativity Space is known for producing rockets using unusual technologies, including 3D printers, automated robots, and artificial intelligence. In 2023, Relativity Space successfully launched the Terran 1 rocket, proving that its 3D printing technology can ...
Electro optical modulators (EOMs) are the main components in optical communication networks, which can control the amplitude, phase, and polarization of light through external electrical signals.In order to achieve ultra compact and high-performance EOM, most of today's research focuses on on-chip devices that combine semiconductor technology with state-of-the-art tunable materials. However,...
