Abstract
The interaction of intense femtosecond duration laser pulses with dense plasmas is replete with new plasma phenomena and exciting experimental opportunities. The intense fields within laser radiation with power levels in 1019 W/cm2 range interacting with dense plasmas leads to the generation of enormous bursts of energetic electons (j ~ 1015 A/cm2) that then give rise to the production of intense hard x-ray emission and unprecedented magnetic fields that could be in the GigaGauss range[1-3]. The role these phenomena play on the particle dynamics in these plasmas poses many interesting questions. As the development of femtosecond laser systems reaches these conditions[4,5] ,the examination of these phenomena becomes possible.
