摘要：
We report one of the first measurements of induced heating due to the transport of a fast electron beam generated by an ultrashort pulse laser interaction with solid targets. Rear-side optical reflectivity and emissivity have been used as diagnostics for the size and temperature of the heated zone. A narrow spot has been observed of the order of the laser focus size. Values up to similar to10 eV at the target back surface were inferred from the experimental data and compared with the predictions of a hybrid collisional-electromagnetic tran-sport simulation.
