Researchers at University of Tsukuba have successfully measured electric fields near the surfaces of two-dimensional layered materials with femtosecond temporal and nanometer spatial resolution. They ...

A team led by EPFL has built a laser on a single photonic chip that fires femtosecond pulses with energy and speed that, until now, required bench-top instruments occupying an entire optical table.

Femtosecond lasers are turning nanostructures into a new kind of thermal hardware, where heat can be sculpted almost as precisely as light. By carving periodic patterns and buried modifications into ...
