Resonance in scattering and absorption from large noble gas clusters

Light scattering in large noble gas clusters irradiated by intense laser pu lses was studied and compared to absorption measurements. The scattering si gnal shows the presence of a peak, when the pulse width was varied, similar to one previously reported in absorption measurements. The peak of the sca ttering, however, occurs at a longer pulse width than for absorption. This result disagrees with a simple simulation and may be due to propagation or non-linear effects not included in the model. (C) 2000 Optical Society of A merica.
