The fast ion emission from high intensity, picosecond laser plasmas has been measured to give the characteristic ion energy and the amount of laser energy transferred to ions with energies [ge]100 keV/nucleon as a function of incident intensity. The characteristic ion energy varies from 0.2 to 1.3 MeV over the range 2.0[times]10[sup 17]--2.0[times]10[sup 18] W cm[sup [minus]2]. Ten percent of the laser energy is transferred into MeV ions at 2.0[times]10[sup 18] W cm[sup [minus]2]. Calculations of stopping power in high density materials are presented that show that fast ions cannot be ignored in modeling fast ignitor schemes.
