Abstract
We report about a detailed study of the dynamics of laser- excited quasiparticles in YBa2Cu3O7-thin films. We propose a model of the low-temperature response which links the reflectivity transients at low temperature to the generation and recombination behavior of quasiparticles. The quasiparticle recombination rate is determined by comparison with a model of the quasiparticle dynamics based on the extended Rothwarf-Taylor equations. The recombination rates in the high-Tc materials are close to the rates of conventional superconductors.
