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...
With funding from the National Science Foundation of the United States, researchers at the University of Rochester are developing photonic chips that use quantum technology called "weak value amplification" to replace mechanical gyroscopes used in drones, enabling them to fly in areas where GPS signals are obstructed or unavailable.Using this quantum technology, scientists aim to provide the same ...
Short wave ultraviolet all solid-state coherent light sources have the characteristics of strong photon energy, practicality and precision, and high spectral resolution. They have significant application value in laser precision processing, information communication, cutting-edge science, and aerospace fields.The core component of obtaining all solid-state shortwave ultraviolet lasers is nonlinear...
High intensity and high repetition lasers rapidly and continuously emit powerful bursts of light, capable of emitting multiple times per second. Commercial fusion energy factories and advanced compact radiation sources are common examples of systems that rely on such laser systems. However, humans are a major limiting factor as their response time is insufficient to manage such rapid shooting syst...
Researchers at the Federal Institute of Technology in Lausanne have resolved the long-standing debate surrounding laser additive manufacturing processes through a groundbreaking defect detection method.The development of laser additive manufacturing is often hindered by unexpected defects. Traditional monitoring methods, such as thermal imaging and machine learning algorithms, have shown significa...
