We demonstrate a novel method of material processing to create flexible periodic structures using temporal pulse shaping of ultrashort laser pulses and spectral interferometry. This scheme is based on the idea that the interferometric fringe pattern at a Fourier spectral plane can be varied by programming temporal amplitude, relative phase and the interval of two collinearly incident pulses. Various periodical patterns are formed on a silicon surface located at the Fourier plane with laser ablation.
