Abstract

The structure of the hot electron beams emitted in laser-solid target interactions was analyzed. It was observed that electron beams were emitted from the rear of thin solid targets irradiated by a high-intensity short-pulse laser. It was shown that the most important condition in which electron beam filamentation due to Weibel-like instabilities become a factor were situations where large regions of low-density plasma exist. The results suggest that Weibel-like instabilities might not be important for the fast-ignitor scheme.
