Title Femtosecond optical detection of quasiparticle dynamics in High-Tc YBa2Cu3O7-δ superconducting thin films
Date 1990-11
Description Femtosecond dynamics of photogenerated quasiparticles in YBa2Cu307-δ superconducting thin films shows at r < Tc two main electronic processes: (i) quasiparticle avalanche production during hot-carrier thermalization, which takes about 300 fsec; (ii) recombination of quasiparticles to form Cooper pairs which is completed within 5 psec. In contrast, nonsuperconducting epitaxial films such as PrBa2Cu3C>7 and YBa2Cu3C>6 show regular picosecond electronic response.
