ResumoMeasurements of laser-driven mass ablation rates are presented for wavelengths of 1.05 μm, 0.53 μm and 0.35 μm. For spherical and plane targets the mass ablation rates scale as I0.7 and I0.3 respectively. The difference is attributed to lateral energy loss on plane targets. Values of ablation pressure are derived.
