It is reported that recently researchers from the Chinese Academy of Sciences have achieved the highest power output of 193 nm and 221 nm lasers using lithium borate (LBO) crystals. This achievement lays the foundation for the further application of the laser in deep ultraviolet (DUV) spectroscopy.The laser in DUV spectroscopy has many applications in science and technology, such as defect detecti...

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 team led by Wu Kaifeng, a researcher at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Zhu Jingyi, an associate researcher, has made progress in the interdisciplinary field of photochemistry and photophysics. The team directly observed the quantum coherence properties of hybrid free radical pairs composed of quantum dots and organic molecules, achieving ef...
