Paper Abstract

We have observed an appearance of a wavelike (ripple) structures on GaAs due to influence of ultrafast (fs) laser pulses. Optical and atomic force microscopy studies revealed the double wavelength characters of ripples inside and outside of the illuminated areas. Raman investigations showed the existence of zinc-blend to cubic transitions in crystalline symmetry at the peripherical part of the irradiated area.
