Anomalous effects on hot-electron transport and ablation structure

摘要: Two features of the ablation structure in presence hot electrons are clarified by simulation and theoretical analysis. One feature is possibility steady deflagration wave being formed collisional energy deposition high-density region laser targets, other one creation a steep density profile near critical point, associated with hot-electron trapping coldelectron heating due to high electric field enhanced anomalous resistivity return current. It should be noted that, this region, significant fraction transferred thermal above 5 × 1015Wcm−2. A analysis given which qualitatively agrees well results. Possible applications theory recent experiments proposed.
