Abstract
In this study, the 1-D hydrodynamic code (MED103) has been used to simulate the Tin (Sn) plasma in space and time with 400 cells as mesh and 10 ns simulation time that is produced by laser with the pulse of 500 fs and its wavelength of 1064 nm. Unique radiation sources of extreme ultraviolet and soft X-ray emissions can be generated from the high ions of laser-produced heavy element plasmas. The spatial-temporal distribution of Sn plasma parameters was studied when a laser pulse was focused on a target to 100 µm diameter with the intensity of 1.27 * 1015 w/cm2. There are two peaks of pressure, first inside the target after laser pulse time and the other close to the surface of the target at a time of 8 ns which is higher than 30 ≈ Mbar. The pressure is still high during simulation time. During and after the laser pulse time, the electron and ion temperature reaches maximum value but their values are not equal.
