Optical metamaterials are an effective way to utilize their superior photon capture capabilities. Therefore, perfect absorbers can be achieved through nanoscale resonant plasmas and metamaterial structures.Metamaterial perfect absorbers (MPAs) are typically composed of periodic subwavelength metals (such as plasma superabsorbers) or dielectric resonance units. Compared with static passive physical...
On quartz sheets, the angular rhombic boron nitride crystals with a thickness of only 1 to 3 microns are as thin as cicada wings, but their energy efficiency is 100 to 10000 times higher than traditional optical crystals. At the opening ceremony of the 2024 Zhongguancun Forum Annual Conference held on April 25th, the world's thinnest known optical crystal was listed as one of the top ten technolog...
Recently, according to Tom's Hardware, Lawrence Livermore National Laboratory (LLNL) in the United States is developing a PW (1015 W) level large aperture thulium (BAT) laser. It is reported that this laser has the ability to increase the efficiency of extreme ultraviolet lithography (EUV) light sources by about 10 times, and may potentially replace the carbon dioxide laser used in current EUV too...
The high-end laser cutting machine developed and produced by Dongying Lijin Zhancheng Laser Intelligent Manufacturing Company has become popular in overseas markets this spring. This equipment can not only use laser to quickly cut steel, but also freely swing on steel, "showing" beautiful pictures. The laser travels like a paintbrush flying, and the hard steel plate has been hollowed out into be...
AAC Clyde Space, a small satellite technology multinational company headquartered in Uppsala, Sweden, has obtained the right to manufacture and distribute laser satellite communication terminals using the optical technology of the Dutch research institution TNO.TNO's technology helps to transmit satellite generated data to Earth through lasers, with the potential to achieve high speed and security...
