Abstract
A new model employing five energy levels and a fit the-varying linear photo-pumping rate of x-ray source is proposed to analyze the gain of inner-shell photo-ionization (ISPI) x-ray laser. The deduced analytical expressions for the time of the onset of the peak gain and its peak value reveal the effects of Auger decay, electron impact ionization, the density of lasing medium and the ratio of statistical weights on the duration and peak value of the laser gain, also the requirements on the intensity of the driving USP laser can be estimated.
