Optical materials and structures are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific ...

Solar background and multiple scattering degrade the profiling depth and ocean-color parameter retrieval of ocean LiDAR. Our anti-interference circularly polarized LiDAR effectively suppresses these ...

Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, ...
