Abstract

The possibility of guiding ultra-short, intense laser pulses in non-ablative capillary discharges is studied. The ablation-free capillary z-pinch provides similar results as the ablative pinch, but it has numerous advantages. It is instability-free, pollution-free and it does not destroy the capillary walls. The pinch dynamics is simulated with a one-fluid, two-temperature (ion and electron) magneto-hydrodynamic code and is compared with experimental results. Experiments were provided on a capillary discharge based apparatus for the soft x-ray laser. The simulation of the dynamics shows, that varying the discharge parameters a parabolic electron density profile, appropriate for guiding the laser pulses, can be reached inside the capillary channel.
