The pump-probe laser system provides a three-dimensional view of any part of a painting without taking a chip. Researchers can zoom in and out, like looking at a layer cake, and separate colors to see ...

The ultrashort pump laser pulse interacts with a 10 nm-thick diamond-like carbon foil (DLC). The interaction region is illuminated with a probe laser pulse with a large optical spectrum, whose various ...

This optical micrograph shows an array of microscopic metamaterial samples on a reflective substrate. Laser pulses have been digitally added, depicting pump (red) and probe (green) pulses diagnosing a ...
