Abstract We demonstrate a novel experimental method for unusual structural surface modification of various solids (PMMA, amorphous carbon) achieved by simultaneous action of XUV (21.6 nm), obtained from high-order harmonic generation, and Vis-NIR (410/820 nm) laser pulses. Although the fluence of each individual pulse was far below the surface ablation threshold, very efficient and specific material expansion was observed after irradiation by a few shots of mixed XUV/Vis-NIR radiation.
