New machine learning algorithm accurately decodes molecular optical 'fingerprints'

Scientists from the Hanover Laser Center (LZH) in Germany are studying two laser based processes for producing load adapted hybrid solid components.From a transaction perspective, mixing semi-finished products can help save materials and production costs, but if the components that need to be replaced are made of expensive materials, these materials need to meet high requirements in future use, su...

Recently, the team led by Professor Lv Zhiwei and Professor Bai Zhenxu from Hebei University of Technology, in collaboration with Professor Richard Mildren from Macquarie University in Australia and Professor Takashige Omatsu from Chiba University in Japan, successfully achieved direct output of Raman vortex optical rotation with large wavelength extension in a diamond Raman laser oscillator. This...

At present, the navigation system has become an important equipment on ships, aircraft, missiles, automobiles and other navigational vehicles. Laser Doppler radar has become an important development direction in the field of velocity measurement technology because of its high accuracy, good spatial resolution and fast dynamic response. The application of the three-beam Doppler Lidar in the...

As far as quantum physics is concerned, one of the most striking predictions is that matter can be produced entirely from light (i.e., photons). Pulsars are an example of an object capable of achieving this feat.In a recent study reported in the journal Physical Review Letters, a research team led by scientists at Osaka University simulated the conditions that allow photons to collide with photons...

Recently, Associate Researcher Zhang Junyong from the High Power Laser Physics Joint Laboratory of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, together with Professor Zhao Yongpeng's research group from Harbin Institute of Technology and Professor Zhan Qiwen's research group from Shanghai University of Technology, completed the experimental verification of 46....
