In this work the effect of main pumped laser pulse parameters on the plasma active medium of a soft x-ray laser is studied. For this purpose we have used a double pulse pumped laser and MED103 hydrodynamic cod to simulate the Neon-like germanium active medium at the Wavelength 19.6 nm. Appling an optimized pre-pulse and by changing main pulse parameters such as intensity, energy and pulse duration, the characteristics of plasma active medium and its ionization are determined. Then gain coefficient of the active medium is calculated. The results of simulations show that to achieve a plasma with maximum soft x-ray laser gain, main pulse of pumped laser should have an optimum pulse duration.
