Using light beams for communication is not a new idea, even outside of Star Trek, Star Wars, and other similar fantasy stories. Scientist and science fiction writer Arthur Clark predicted that beam communication, at that time modern satellite communication was just a dream.In 1975, the magazine published an article about laser communication or laser communication equipment. The demonstrati...
In recent years, with the vigorous development of new energy and other industries, the improvement of environmental awareness and the increasing demand for new applications, the demand for fiber lasers in intelligent manufacturing is increasing, and the demand for power is also increasing, and high-power fiber lasers can significantly improve production efficiency and are widely sought after by th...
μ Mesons are naturally occurring subatomic particles that can penetrate much deeper dense matter than X-rays. Therefore, μ Meson imaging can enable scientists to capture images of nuclear reactors, volcanoes, tsunamis, and hurricanes. However, this process is slow, as it occurs naturally μ The low flux of mesons requires several months of exposure time for the image.It is understood that ...
Around the poles, ice accumulated over millions of years can reach depths of several kilometers. The undisturbed deep ice preserves information about the past. The air bags and particles trapped in the ice tell scientists what the atmosphere used to be like. This has aroused great interest among paleoclimatologists in glacier ice cores.By regularly sampling the ice core at its depth, they can reco...
Zhao Yun/Columbia Engineering Company provided an advanced schematic of a photonic integrated chip, which aims to convert high-frequency signals into low-frequency signals using all optical frequency division.Scientists have built a small all optical device with the lowest microwave noise ever recorded on integrated chips.In order to improve the performance of electronic devices used for global n...
