On quartz sheets, the angular rhombic boron nitride crystals with a thickness of only 1 to 3 microns are as thin as cicada wings, but their energy efficiency is 100 to 10000 times higher than traditional optical crystals. At the opening ceremony of the 2024 Zhongguancun Forum Annual Conference held on April 25th, the world's thinnest known optical crystal was listed as one of the top ten technolog...
In a study published in Optics Express, the research team led by Professor Fu Yuxi of the Xi'an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences developed the room temperature holmium doped lithium yttrium fluoride (Ho: YLF) composite thin slice laser for the first time, which can achieve high efficiency and high-quality CW laser output.Laser devices operating...
A Boston University research project has successfully developed an innovative single-cell sorting technique that uses stimulated Raman spectroscopy to replace traditional fluorescent labeling and achieve labeling free and non-destructive single-cell measurements. This technology is expected to have a profound impact in the fields of cytology, microbiology and biomedical research, allowing scienti...
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...
Researchers at the University of Bristol have made significant breakthroughs in expanding quantum technology by integrating the world's smallest quantum photodetector onto silicon chips. The paper "A Bi CMOS Electron Photon Integrated Circuit Quantum Photodetector" was published in Science Advances.In the 1960s, scientists and engineers were able to miniaturize transistors onto inexpensive microch...
