Abstract
By solving the Maxwell equations, an effective plasma dielectric constant i s obtained to replace the quasistatic plasma dielectric constant derived fr om the Drude model. In the vicinity of resonance absorption, the electron d ensity and temperature undergo such a rapid change that the quasistatic die lectric constant is no longer appropriate to describe the behavior of reson ance absorption. Using this effective dielectric constant to modify the hyd rodynamic model developed by Ditmire and co-workers, we studied the interac tion between different-sized atom ic clusters and high-intensity laser puls es of different wavelengths. Reasonable agreement between the calculated re sults and published experimental results was found.
