摘要：

Measurements of electron energy distributions from ultraintense (>10(19) W/cm(2)) laser solid interactions using an electron spectrometer are presented. The effective hot electron temperatures (T-hot) have been measured for laser intensities (I lambda(2)) from 10(18) to 10(21) W/cm(2) mu m(2) for the first time, and T-hot is found to increase as (I lambda(2))(0.34 +/- 0.04). This scaling agrees well with the empirical scaling published by Beg [Phys. Plasmas 4, 447 (1997)], and was modeled by particle-in-cell simulations.
