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 ...

Fig. 1 (a) Confocal optical microscopy image of LSFL prefabricated on silicon surface. (b) Experiment setup of the collinear pump-probe imaging system. (c) Spectra of the white-light pulse with (red ...

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 ...
