    This paper is devoted to determination of the plasma ablative pressures for ablators with different atomic numbers. For this reason several target materials with a wide range of atomic numbers (Z = 3.5-73), i.e. plastic (CH), Al, Cu, Ag and Ta, were used. To compare pressures of plasmas produced from various materials, the targets consisted of two components. One of them, in the form of a cylindrical insert 200 mu m in diameter, was fixed to the second one. The targets were irradiated by the third harmonic of the Prague Asterix Laser System (PALS) laser radiation with the energy of 130 J and focal beam diameter of 600 mu m on the target surface. The results presented show that the plasma pressure decreases with increasing atomic number, but in a limited range of Z only. For higher Z, starting approximately from Z = 47 (Ag), the plasma pressure becomes constant, as confirmed by interferometric measurements.
