High power laser diodes will be key components of future fusion power plants.Recently, the German Federal Ministry of Education and Research (BMBF) launched a new project called "DioHELIOS". The project will last for 3 years and is part of BMBF's "Fusion 2040" funding program, which aims to build the first nuclear fusion power plant in Germany by 2040.The project will last for three years and rece...
Recently, the team led by Professor Lv Zhiwei and Professor Bai Zhenxu from Hebei University of Technology, in collaboration with Professor Richard Mildren from Macquarie University in Australia and Professor Takashige Omatsu from Chiba University in Japan, successfully achieved direct output of Raman vortex optical rotation with large wavelength extension in a diamond Raman laser oscillator. This...
With the increasing demand for human data, the requirements for data storage methods are also increasing. Optical Data Storage (ODS) is a light based storage method commonly used in DVDs, which is low-cost and very durable. But ODS usually stores data in a single layer, and the amount of data that can be stored is limited. Gu Min, academician of Shanghai University of Technology, Wen Jing, and Rua...
On January 13, 2025, Thorlabs announced the acquisition of long-term partner Praevium Research, a developer of high-speed tunable VCSEL. In the future, Praevium will continue to operate as a department of Thorlabs under the name Praevium Research at its existing locations in California, while retaining its current leadership.It is understood that Christopher Burgner will serve as the general man...
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...
