英文摘要	a model employing five energy levels and a fit linear rising photopumping rate of x-ray source is proposed to analyze the gain of inner-shell photoionization (ispi) x-ray lasers when the lasing medium is irradiated with a filtered approximate blackbody source. 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 increase rate of pumping rate on the duration and the peak value of the laser gain. also the requirements on the intensity of the driving ultrashort pulse laser can be estimated. the model is generally suitable for analyzing ispi x-ray lasers in low-z elements from carbon to neon although carbon is analyzed in details as a representative to verify the validity of the model. k alpha x-ray lasing at 3.2 nm in nitrogen is also discussed as an attractive candidate for experimentally implementing a "water window'' ispi x-ray laser.
