Iron Triangle releases fiber Bragg gratings and arrays based on multi-core fibers

Researchers at the Technion-Israel Institute of Technology have developed a coherently controlled spin optical laser based on a single atomic layer.This discovery was made possible by coherent spin-dependent interactions between a single atomic layer and a laterally constrained photonic spin lattice, which supports a high-Q spin valley through Rashaba-type spin splitting of photons of bound states...

Recently, the research team of Yang Shanglu from the Laser Intelligent Manufacturing Technology R&D Center of the Chinese Academy of Sciences Shanghai Institute of Optics and Precision Machinery has made new progress in laser welding of new structural materials for high-temperature molten salts. The research team used a high-power laser for the first time to achieve defect free welding of nick...

In 2017, the detection of gravitational waves generated by the merger of binary neutron stars marked a significant breakthrough in physics. These waves reveal important information about the universe, from the origin of short gamma ray bursts to the formation of heavy elements.However, capturing gravitational waves from the merged residue remains a challenge as these waves avoid the detection rang...

Recently, the High Power Laser Physics Joint Laboratory of Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, completed the research of hard X-ray zoom beam splitting imaging on the micro focus X-ray source for the first time, and solved the problem of beam splitter limitation in the hard X-ray band. The related achievements are titled "Bifocal photo scene imaging in the...
