Abstract
In order to investigate the production of plasma with simultaneous high density and high degree of ionisation and to study laser-plasma energy transport, experiments have been undertaken to measure the plasma electron densities formed in a thin layer of aluminium buried below an overlay of plastic when the plastic overlay is irradiated by focussed lasers of wavelength (and pulse length).53tm (2Ops) ; .35im (2Ops) and .27 pm (5Ops) . For the .53im and .35pni wavelengths, the shorter pulse length (2Ops) results in higher time-averaged electron densities (up to 6 x 1022 cm3) than for the .27tm wavelength experiments with 50 ps pulse length, but the production of hydrogen-like aluminium relative to helium-like is less with the shorter pulse-length.
