Ultrafast time resolved imaging of femtosecond laser induced periodic surface st
We report the formation dynamics of periodic ripples on GaAs induced by femtosecond laser pulses (800 nm, 50 fs) via a collinear time-resolved imaging technique with a temporal resolution of 1 ps and a spatial resolution of 440 nm. The onset of periodic ripples emerges in the initial tens of picosec
