Abstract A grazing incidence pumping x-ray laser scheme using JIGUANG II is proposed. We investigate the characteristics of the focusing of parabolas, and obtain the optimal intensity distributions in the target
surfaces with paraboloid mirrors of different parameters by the vectorial ray-tracing. Kinetic simulations are carried out. The results show that due to the enhancement of absorption by the selectable plasma
region (gain region), saturated amplification of the x-ray laser can be achieved with 100mJ energy in pre and pumping pulses, respectively, on 3mm Ti targets.
