Muon beams can now be created in a device that is the length of a ruler. Researchers at Berkeley Lab presented a foot-long (30 cm) compact laser-plasma accelerator (LPA) that can generate and detect ...

Lasers that emit extremely short light pulses are highly precise and are used in manufacturing, medical applications, and research. The problem: efficient short-pulse lasers require a lot of space and ...

Lasers in conventional laser printers for paper printouts are very small. 3D laser printers for 3-dimensional microstructures and nanostructures, by contrast, have required big and expensive laser ...
