A new beam pattern could bring unprecedented sharpness to ultrasound and radar images, burn precise holes in manufactured materials at a nano scale -- even etch new properties onto their surfaces. A ...

Whorls of FLASH: (a) Optimized scan patterns; (b) comparison of standard (non-optimized) line-by-line and scan-pattern optimized (SPO) patterns. The resulting pencil-beam scanning dose rate (PBS-DR) ...

Beams of light polarized into spirals have been used by scientists in the UK to create intricate patterns on the surface of metals. This is the first time that these “logarithmic spirals” have been ...

Gaussian-shaped laser-beam frequency spectrum can now be translated into a collimated flat-top beam that propagates with little change in power and intensity or loss of uniformity over large distances ...

The Nobel Prize in Chemistry 2014 was awarded for the development of super-resolved fluorescence microscopy. Inspired by this work, scientists at Institute of Photonic Chips (IPC), University of ...
