Si and Cu targets were ablated by a capillary-discharge 46.9-nm pumped laser beam, focused by a toroidal mirror at grazing incidence. The peak power density of the focal spot was ~2 × 10 7 W/cm 2 . Clear ablation patterns on the surfaces of Si and Cu targets were obtained, with shapes consistent with simulations.
