Site selective bond breaking in random media

We show that strong light with the frequency slightly less then the 'gap' in electron spectrum of fused quartz cuts off macroscopic balls with fixed diameter 2 ± 0.2 μm and throws them out of the ablation crater. The reason for the phenomenon is the light driven electron bunching and generation of strong static electric field on the bunch boundaries resulting in effective photon absorption and bonds breaking in these regions while the main part of a sample is almost transparent for the photons.
