Abstract
The inverse Laplace transformation method was used to interpret the time-re solved emission spectra of Sr* and describe the dynamics of the laser plume formed in the laser ablation of Pb-Bi-Sr-Ca-Cu-O. Three kinds of processes characterized by rate constants b(1), b(2) and b(3) were found in the lase r plume. The rate constant of the slowest process b(3) increases with the p ressure and can be assigned to deexcitation of Sr*. The next two rate const ants b(1) and b(2) describe processes occurring during the laser pulse and immediately after it.
