Abstract :
The recently published experimental results about influence of femtosecond laser on widebandgap dielectrics are discussed in this paper. We propose the possible mechanism of formation regular microvoids along filament path inside glass, based on interference of surface plasmon-polaritons on boundary metallized dielectric-glass in condition of nonthermal phase transition in dielectric.
