Wavelength effects on hot electron generation at relativistic intensities*

Ultraintense laser interactions with solid density plasma involve significant transfer of energy to electrons. The energy and angular distribution of these electrons play a vital role in the Fast Igniter approach to Inertial Fusion Energy. To investigate the hot electron dependence on irradiation conditions, slab and buried-cone targets were shot on the Titan laser with 1054 and 527 nm short pulse light with 50-150 J of laser light, and intensities greater than 10$^{19}$ Wcm$^{-2}$. Experimental and hybrid PIC results of escaping electrons will be presented.
