Abstract
The level of second-harmonic light emitted from a laser-exploded foil plasma at nominal irradiance up to 3-1013 W/cm2 was found to be extremely sensitive to both target position and irradiance on target. Either a small target displacement or a small increase in irradiance resulted in a jump of the 2tu level of more than three orders of magnitude. Correspondingly, a transition was observed from a 2File in questo prodotto:
