A computational investigation of nickel - like dysprosium collisionally pumped laser

Abstract

The Ni-like Dy X-ray laser at 5.86 nm is investigated in detail using the 1.5-dimensional fluid and atomic physics code EHYBRID. Directly measurable parameters are calculated using the combined optical raytracing and saturation calculation code RAYTRACE. The energy output of a Ni-like Dy X-ray laser as function of plasma length and the peak-to-peak time separation between the main 1 ps pulse and 300 ps background pulse simulated using a combination of the EHYBRID with RAYTRACE codes. The intensity of resonance line and continuum emission between 0.5 and 1.5 nm emitted from dysprosium plasma are simulated using the development of a post-processor to the modified EHYBRID code. The spatial profile with distance from the target surface of electron density N_e, electron temperature T_e, fluid velocity v and gain coefficient are simulated by the EHYBRID code.
