We achieved a relative optically thin state in laser-produced heavy element plasmas at determined electron temperatures, which has been predicted by the power balance and the collisional-radiative models. We also mapped the power-loss processes in sub-ns and ns laser-produced high-Z plasmas. The electron temperature evaluation was in good agreement with the power balance model and was supported by the spectral analysis. The output flux in the soft x-ray region was stronger at higher critical density.
