Abstract: The paper presents a concept of laser fragmentation of metal nanoparticles in liquids by nanoseconds pulses and demonstrates evolution of individual fractions in the nanoparticle size distributions. The concept is based on the capillary-wave mechanism for the formation of fractions of fragments of initial particles. The presented results of theoretical simulation are in good agreement with the experimental data.

Keywords: capillary waves, nanoparticles, laser fragmentation, absorption cross section, dispersion, distribution.
