| Abstract: | Total and specular reflection from planar Al-targets was measured with a frequency-quadrupled (λ = 0.26 μm) Nd-YAG laser. The intensity on target was 4 × 1013 W/cm2 with pulse duration 20 ps. Total absorption for near normal incidence was 80%, very little dependence on intensity and pulse duration was found. By varying the polarization and angle of incidence (0°–80°) the characteristic behaviour of resonance absorption was observed. |
