Description
First observed visible harmonics of CO2-laser-irradiated plane and microballoon targets are reported. For intensities >5 x 1014 W/cm2, the harmonic production efficiency is constant over several visible harmonics with a cutoff at a high harmonic number. Two-dimensional particle simulations performed where there is a highly steepened density profile show a flat spectrum for high harmonics, with a cutoff at the harmonic where the upper density shelf is underdense. Harmonics thus offer a means of measuring the upper density shelf and its dynamics
