A few days ago, DR laser released 2024 half-yearly report, the company realized operating income of 906 million yuan in the first half of the year, a year-on-year increase of 34.40%; net profit of 236 million yuan, a year-on-year increase of 35.51%. For the reasons of performance growth, DR laser said in the half-yearly report, the company's first half of the order continued to acceptance brough...
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...
The project of the National Natural Science Foundation of China (Jilin Province) "Multicolor Transparent Silicate Garnet Fluorescent Ceramics for Laser Lighting" presided over by Zhang Jiahua, a researcher in the State Key Laboratory of Luminescence and Applications of Changchun Institute of Optics and Fine Mechanics, has made breakthrough progress, developed green fluorescent transparent ceramics...
Recently, the research team of the State Key Laboratory of Intense Field Laser Physics of the Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics has made progress in the research on the nonlinear behavior and mechanism of platinum selenide in terahertz band. The research team systematically studied the spectral and optical intensity characteristics of platinum selenide und...
Recently, a team of Professor Ruan Shuangchen and Professor Zhou Cangtao from Shenzhen University of Technology proposed for the first time internationally a physical solution based on the generation of attosecond pulses and subperiodic coherent light shock radiation from a superluminal plasma wake field, and explained a new coherent radiation generation mechanism dominated by collective electron ...
