A study of the variation of the effective ablation pressure with thickness of laser irradiated thin gold foils is presented. Gold foils (2.5 and 12.0 µm thick) were irradiated by a glass laser (1.06 µ m wavelength, 5 ns pulse duration) in 1011-1013 W/cm2 irradiance range. Ablation pressure and its scaling is found to be higher for the 12 µm-thick gold target. The results are consistent with other results obtained on the basis of enhanced x-ray transmission through thin gold foils. Theoretical estimates of the x-ray transport are carried out to support this.
