Polished aluminum targets were irradiated with 1.06-..mu..m laser pulses of 60-psec and 2.5-nsec duration and of ..pi.. and sigma polarization. The peak focused intensity was varied over the range 10/sup 14/-10/sup 16/W/cm/sup 2/. Clear evidence of resonant absorption for 60-psec pulses was obtained from target momentum measurements made with a torsion pendulum. No resonant absorption effects dependent on light polarization or angle of incidence were detected for long-pulse irradiations.
