Enhanced laser heterodyne spectroscopy contributes to the measurement of atmospheric greenhouse gases

The Chinese Academy of Sciences reduced the volume of the deep ultraviolet laser by 90% and achieved 193 nm vortex beam output for the first time. Professor Xuan Hongwen described "loading truck equipment into the car trunk". This technology enables a 30% reduction in the size of lithography features, breaking through the bottleneck of the 2-nanometer process. In the next three years, laser power ...

It is reported that the National Institutes of Sciences (INRS) of Canada has developed a camera platform that can achieve cheaper ultra fast imaging through the use of ready-made components, which can be used in various applications.This new device aims to address some of the limitations of current high-speed imaging, including parallax errors and potential damage from pulse illumination. Th...

Physicists at the University of Oxford have unveiled a “pioneering” method for capturing the full structure of ultra-intense laser pulses in a single measurement. The breakthrough, a collaboration with Ludwig-Maximilian University of Munich and the Max Planck Institute for Quantum Optics, could revolutionize the ability to control light-matter interactions, say the team.The Oxford announcement sta...

Electro optical modulators (EOMs) are the main components in optical communication networks, which can control the amplitude, phase, and polarization of light through external electrical signals.In order to achieve ultra compact and high-performance EOM, most of today's research focuses on on-chip devices that combine semiconductor technology with state-of-the-art tunable materials. However,...

Recently, Hu Lili, a research team of the High Power Laser Unit Technology Laboratory of the Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics, used a method combining experiment, molecular dynamics simulation and quantitative structure property relationship analysis (QSPR) to study aluminum phosphate glass, and the related research results were published in the Journal o...
