The scattering and absorption of a high-power picosecond laser pulse by a solid target were investigated experimentally making use of the 'Progress-P' Nd:glass laser facility ({lambda} = 1053 nm, {tau} = 1.4 ps) at radiation intensities I = 10{sup 16} - 10{sup 19} W cm{sup -2} on the target surface. It was found that, for I {<=} 10{sup 17} W cm{sup -2}, more than 30% of the intensity of the scattered light was contained in the specularly reflected component. The absorption coefficient of the laser radiation with intensities ranging from 10{sup 18} to 10{sup 19} W cm{sup -2} was higher for targets made of materials with higher atomic numbers.
