Recently, Afinum Management, a private equity firm based in Munich, Germany, has acquired a large stake in two laser companies, with the intention of opening up new laser markets by combining the strengths of three parties.According to media reports, the two companies are ARC Laser in Germany and GNS neo Laser in Israel, and Afinum has agreed with the founders of the two companies that the acquisi...
Headdisplay devices such as Apple Vision Pro, Meta Quest, and PICO are expected to completely change the way we perceive and interact with various digital information. By providing more direct interaction with digital information, MR has become one of the key driving forces for the metaverse, spatial computing, and digital twins, and has begun to be widely applied in fields such as intelligent tou...
Recently, the team of Situ Guohai and Guo Jinying from the Aerospace Laser Technology and Systems Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, and the School of Microelectronics at Shanghai University collaborated to propose a terahertz phase controlled programmable metasurface design scheme based on free carrier plasma dispersion effect. The rela...
With the development of groundbreaking components for terahertz quantum cascade lasers, a huge leap has been made in the field of laser technology. A group of researchers have successfully designed a broadband single-chip external coupler with the potential to redefine the functionality of terahertz QCL.The new external coupler is fundamentally based on planar bimetallic waveguides. Its design is ...
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 ...
