A precise measurement of absolute beam intensity is essential for many areas of science. It is a key parameter to monitor any losses in a beam and to calibrate the absolute number of particles ...

Self-accelerating beams—shape-preserving bending beams—are attracting great interest, offering applications in many areas such as particle micromanipulation, microscopy, induction of plasma channels, ...

If you could hold a giant magnifying glass in space and focus all the sunlight shining toward Earth onto one grain of sand, that concentrated ray would approach the intensity of a new laser beam. The ...
