Modern laser technology urgently requires nonlinear optical materials that can generate coherent light through second harmonic generation. However, only a small portion of the nonlinear optical properties of non centrosymmetric crystal materials have been experimentally or theoretically studied, and exploration for high-performance nonlinear optical crystal materials is still very limited.Recentl...
Recently, the Jiang Haihe Research Group of the Health Institute of the Chinese Academy of Sciences Hefei Institute of Materia Medica made important progress in the research of the high-energy pulsed laser transmission system in the mid infrared band, and designed a 78 μ The 6-hole microstructure anti resonant hollow core fiber (AR-HCF) with a larger core diameter achieved efficient transmissio...
When researchers at the Max Planck Institute of Medicine conducted their first ultrafast X-ray crystallographic experiment on myoglobin in 2015, they were not aware that they had conducted the wrong experiment. By increasing the power of X-ray free electron lasers to ensure usable diffraction patterns, lead researcher Ilme Schlichting said that they "suddenly entered the wrong [excited] state with...
Recently, NASA's official website showed that a research team at the University of Central Florida has tested an instrument called Ejecta STORM, which aims to measure the size and velocity of surface particles generated by exhaust gases from rocket powered landers on the moon or Mars.According to NASA, when a spacecraft lands on the moon or Mars, rocket exhaust plumes can produce efflorescent ejec...
