摘要：

A YAG laser of 266 run is focused just above or at the surface of a Ni substrate in a near critical CO2 chamber. Since the comprrssibility of CO2 becomes very high, strong shock waves may be produced by laser irradiation. We are going to investigate the dependence of the nano structures for nickel and CO2 on the laser power and the focus point. After the laser radiation, we found fine grains on the Ni substrate with a scanning electron microscopy and energy dispersive X-ray spectroscopy.
