Numerical study of the Ne-like Cr x-ray laser at 28.6 nm

We investigate the Ne-like Cr x-ray laser at 28.6nm by using a modified 1D lagrangian hydrodynamic code MED103 coupled with an atomic physics data package and a 2D ray tracing code as a post-processor. The laser pumping configuration includes two prepulses and one main pulse. The first prepulse normally irradiates the target, while the second prepulse and the main pulse irradiate the target at grazing-incident angles. We predict that saturation can be achieved for the Ne-like Cr x-ray lasers with a total pumping energy of 125mJ. Good beam qualities with no deflecting angle and a small divergence angle of 5mrad are observed. (classical areas of phenomenology)
