Abstract

The plasma ejected by a pellet irradiated with moderately intense laser light (Icrλ2 ∼1015 W cm−2 μm2, Icr and λ being intensity and wavelength) is analyzed. Both hot electrons caused by resonant absorption, and cold or thermal electrons are considered; no appeal is made to heat‐flux saturation. The cold (hot) population controls the overdense (underdense) plasma flow. Ingoing hot electrons at the critical surface are found to thermalize before reaching the ablation surface. Results obtained are compared with a model that assume one electron temperature, and a saturated flux; agreement requires using a range of saturation factors: 0.1≲f≲0.3. The validity of the model is discussed.
