OLED is located at the top and is formed by an organic layer between the contacts. Apply voltage to it, inject charge and generate light, which in turn excites organic laser. Organic lasers contain a grating that can generate feedback and diffract some of the laser out of the structure.Organic laserResearchers have created the first organic semiconductor laser to operate without the need for a sep...
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...
Researchers at the University of St. Andrews in Scotland have manufactured the first organic semiconductor laser to operate without the need for a separate light source - which has proven to be extremely challenging. The new all electric driven laser is more compact than previous devices and operates in the visible light region of the electromagnetic spectrum. Therefore, its developers stated that...
BMW explained how to use WAAM (Arc Additive Manufacturing) starting from 2025 to manufacture lighter and stronger automotive components and reduce waste generation, in order to optimize the use of generative design tools.The demonstrated WAAM process uses aluminum wire raw materials directly deposited through laser welding heads, enabling automotive companies to manufacture lighter and more robust...
Recently, Liang Xu's team from the Laser Center of Anguang Institute, Chinese Academy of Sciences, Hefei Institute of Materia Medica, conducted research on corona discharge fluid control and its application in the gas laser system, proposed an electric field flow field coupling analysis model suitable for multi pin corona discharge scenarios, and revealed the flow velocity distribution characteris...
