Abstract

An experiment was performed on the Shenguang III prototype laser facility to con?tinue the study on hohlraum radiation source with approximately constant radiation temperature using a continuously shaped laser pulse. A radiation source with a flattop temperature of about 130 eV that lasted about 5 ns was obtained. The previous analytical iteration method based on power balance and self-similar solution of ablation was modi?ed taking into account the plasma movements and it was used to design the laser pulse shape for experiment. A comparison between experimental results and simulation is presented and better agreement was achieved using the modi?ed method. Further improvements are discussed.
- X-ray radiation source,
- laser pulse shaping,
- power balance
