Using ensembles of dielectric nanoparticles in the FROG technique

We have implemented the FROG (frequency-resolved optical gating) technique for the characterization of ultrashort laser pulses in the range of tens of femtoseconds using ensembles of dielectric nanoparticles as the non-linear material for SHG (second-harmonic generation). In order to measure traces...
