Figure 2: (A) Time-resolved scattering optical image shows individual transient PNB generated around NP cluster exposed to the two simultaneous laser pulses (0.5 ns each, 532 nm and 787 nm); (B) the profile of pixel image amplitude for the image shown in A, and (C): corresponding time response (obtained for the same PNB simultaneously with the image A) shows PNBspecific dip-shaped signal and characterizes maximal diameter of the PNB.
