Researchers have developed a 60 milliwatt solid-state DUV laser with a wavelength of 193 nanometers using LBO crystals, setting a new benchmark for efficiency values.In the fields of science and technology, utilizing coherent light sources in deep ultraviolet (DUV) regions is of great significance for various applications such as lithography, defect detection, metrology, and spectroscopy. Traditio...
The National Science Foundation (NSF) of the United States has awarded the University of Rochester nearly $18 million for three years to design and prototype key technologies for EP-OPAL, a new facility dedicated to studying the interaction between ultra-high intensity lasers and matter.After the design project is completed, the facility can be built at the Laser Energy Laboratory (LLE). This fund...
Recently, researcher Zhang Wenfu from the National Key Laboratory of Ultrafast Optical Science and Technology of Xi'an Institute of Optics and Mechanics, researcher Chen Wei from the academician team of Guo Guangcan from the Key Laboratory of Quantum Information of the Chinese Academy of Sciences of the University of Science and Technology of China, and professor Yang Jun from the School of Intell...
An interdisciplinary research group, including the German synchrotron radiation accelerator DESY and the Helmholtz Institute in Jena, Germany, reported that invisible gratings made of air not only are not damaged by lasers, but also maintain the original quality of the beam. The relevant research has been published in Nature Photonics under the title of "Acousto opt modulation of gigawatt scale la...
In a significant leap in quantum nanophotonics, a team of European and Israeli physicists introduced a new type of polarized cavity and redefined the limits of light confinement. This groundbreaking work was detailed in a study published yesterday in Natural Materials, showcasing an unconventional photon confinement method that overcomes the traditional limitations of nanophotonics.For a long time...
