The effects of black paint on laser induced shock waves in the aluminum and copper targets are introduced when the targets are irradiated by laser pulses of 33ns duration, at laser power density around 10E９W/cm(cm， and wavelength 1.06μｍ. The direct shock pssure measurements show that the black paint can increase the shock pssure amplitude and affect the shock evolution characteristics as well. The black paint can also protect target surfaces from laser ablation by comparing the SEM photographs of the target surfaces with that without black paint．
