Scientists at the Technical University of Munich have made significant progress in measuring the Earth's rotation with unprecedented accuracy. Now, the ring laser from the Wettzell Geodetic Observatory can be used to capture data at a quality level unmatched anywhere in the world. These measurements are crucial for determining the position of the Earth in space, assisting climate research, and imp...
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...
Recently, the High Power Laser Unit Technology Laboratory of Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made progress in research on high efficiency supercontinuum in specific bands. The relevant research results were published in the Journal of Lightwave Technology under the title of "Strong Anti Stokes and flat supercontinuum in specified band based on non ...
