Conservation of energy is a fundamental concept in physics that can be used to explain anything from planetary orbits to the internal workings of individual atoms.Energy can be converted into other forms, but the overall energy level is usually considered to vary over time. Therefore, when attempting to describe a system, physicists usually pay attention to ensuring that it is isolated from the su...
IntroductionVortex beams carrying orbital angular momentum (OAM) are widely used for high-throughput optical information multiplexing, and achieving on chip, small-scale vortex lasers is crucial for promoting the industrial implementation of vortex light reuse technology. Recently, Gu Min, an academician of Shanghai University of Technology, and Fang Xinyuan, an associate professor of Shanghai Uni...
Scientists from the University of Hahn in Spain and the University of Santiago de Compostela conducted research to determine the most suitable semiconductor materials for high-power light transmission in terrestrial and underwater environments.HPOT, also known as laser power transfer, is a method of transmitting continuous power to a remote system using a monochromatic light source through an opti...
