Researchers from Tsinghua University have summarized the research on ultrafast laser micro nano manufacturing technology, including material processing, surface/interface control, and device manufacturing. The relevant review titled "A Review of Ultrafast Laser Micro/Nano Fabric: Material Processing, Surface/Interface Control, and Device Fabric" was published in Nano Research.Ultra fast laser proc...
The optical properties of afterglow luminescent particles in mechanical luminescence and mechanical quenching have attracted much attention in various technological applications. A group of researchers from Pohang University of Science and Technology has attracted attention by developing an optical display technology with ALP that can write and erase messages underwater.The team is composed of Pro...
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,...
Laser Network reported on January 11th that modern equipment has been fine tuned to detect highly specific gases, including trace gases found in the atmosphere, gases present in combustion exhaust emissions, and gases used in technology plasma applications.They achieve this by calculating the percentage of light at a certain wavelength that is absorbed or attenuated by the sample. This way, the co...
