Ultraviolet spectroscopy plays a crucial role in the study of electronic transitions in atoms and rovibronic transitions in molecules. These studies are crucial for the testing of fundamental physics, quantum electrodynamics theory, determination of fundamental constants, precision measurements, optical clocks, high-resolution spectroscopy supporting atmospheric chemistry and astrophysics, and str...
JQ LASER, a global manufacturer specializing in laser cutting machines, has launched a new fully automatic pipeline laser cutting machine model T120A.According to JQ LASER's report on the 16th, the body of this new product adopts a vertical rather than horizontal design, reducing the machining center and improving stability.In the past, traditional double chuck pipe cutting machines had a fixed fr...
Recently, Zhang Xin's research team from the Institute of Oceanography, Chinese Academy of Sciences, based on the in-situ laser Raman spectroscopy technology, made new progress in the in-situ recognition and quantification of methane carbon isotopes by using the significant differences in the Raman spectra of methane carbon isotopes (13CH4 and 12CH4). The relevant results were recently published i...
Shijia Photon disclosed its 2024 annual performance forecast on the evening of January 17th, expecting to achieve a revenue of 1.074 billion yuan in 2024, a year-on-year increase of 42.36%; Net profit attributable to the parent company was 65 million yuan, with a loss of 47.55 million yuan in the same period last year; Deducting non net profit is expected to be 48.1 million yuan, with a loss of 66...
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 ...
