Theoretical Research on Ni-like Ag X-ray Laser by Grazing Incidence Pumping

Summary

LLNL proposed a conception of grazing incidence technique using short pulse and realized saturated output of Ni-like Pd x-ray laser using only 450 mJ driving energy. We think that this kind of technique may be adapted to quasisteady state (QSS) collisional scheme with 100ps driving laser. In this paper using our series code Ni-like Ag 13.9 nm XRL driven by laser two 100 ps pulses with grazing incidence was studied. Two different main pulses with intensity of respectively 1.2x10¹³ Wcm^-2 and 4.3x10¹³ Wcm^-2 were considered and optimization to grazing incidence angle φ and time interval t12 was made. And comparisons were made with models with the same pumping conditions except rthat the main pulse came normally with varying t12.
