Abstract
We present a detailed investigation of the dynamics of laser-excited q uasiparticles in YBa2Cu3O7 thin films below the critical temperature. Reflectivity transients at low temperature trace the generation and re combination behavior of quasiparticles. The quasiparticle cascading an d recombination rates are determined by comparison with a detailed non linear model of the quasiparticle dynamics based on extended Rothwarf- Taylor equations.
