X-ray and ion emission characteristics of plasmas ablated from solid materials using a high power Nd : Glass laser
X-ray and ion emissions from high temperature plasmas from solid targets with different atomic numbers have been studied. Plasma is generated using a high power Nd:Glass laser generating focused intensity in the range of 10(12) to 10(13) Watts/cm(2) on targets. Plasma temperature is typically between 50 to 100 eV. X-ray emission scaling as a function of laser intensity as well as ion velocity has been measured in these targets. Non-uniform plasma expansion and generation of fast ions are observed for targets with higher atomic numbers. (c) 2006 Springer Science + Business Media, Inc.
