Аннотация:Non-linear cumulative self-organization dynamics of femtosecond laser-induced surface relief
ripples was for the first time experimentally revealed on a silicon surface as their primary
appearance, degradation and revival, reflecting ultrafast non-linear dynamics of corresponding
optical interference surface patterns. Such dynamics were revealed by electrodynamic modeling
to be directly driven by related instantaneous surface optical patterns, which are sensitive
not only to cumulative ripple deepening (steady-state feedback factor), but to laser-induced
instantaneous variation of surface dielectric function, providing either positive or negative
fluence-dependent optical feedbacks
