The induction of surface cleavage along the crystalline structure of a zinc oxide substrate (plane orientation 0001) by femtosecond laser pulses (wavelength 1030 nm) has been reported; a scanning electron microscope image of the one-pulse (pulse energy 6-60 μJ) irradiated surface shows very clear marks from broken hexagons. This cleavage process differs from the general laser-induced melt process observed on the surfaces of narrower-bandgap semiconductors and other metal materials. This phenomenon is discussed using a multi-photon abs
