Characteristics of Ablation Plasma from Planar, Laser-Driven Targets

摘要

The momentum, energy, and velocity characteristics of plasma ablating from planar targets irradiated by long Nd-laser pulses (4-nsec, < 10 to the 14th power W/sq cm) are measured and the dependence of ablation parameters upon absorbed irradiance is determined. Large laser spots are used in these experiments so that the results are not sensitive to boundary effects. (Author)
