Paper Abstract

The interaction of an Excimer laser with an aluminum surface was studied by a characterization of the blowoff plasma plume. The SDIOIMLI Two-Meter Laser, operating at XeF and KrF wavelengths, was used to illuminate mm sized spots on aluminum targets at fluences of 400 - 1250 J/cm2 for 1 .8 ps. The resultant plasma was characterized by numerous techniques. The temperature of the plasma as a function of distance out in the plume was measured by both a modified line reversal technique and spectral methods. The absolute ion density was measured as a function of distance out in the plume by a laser absorption technique. The temperature in the blowoff plasma plume was found to be relatively constant, dropping by approximately 50% in 1 cm. The density, however, fell by an order of magnitude in the same distance. The measured results agree with predictions from the 2-D Hydrocode STREAK.
