Abstract Using an autocorrelation method we studied the voltage photoresponse of a current-carrying superconducting YBa2Cu3O7−δ film excited by femtosecond near infrared radiation pulses. Near the transition temperature we found a picosecond response time consistent with the energy relaxation of nonequilibrium quasiparticles. We also observed a subpicosecond component of the voltage response which we attributed to the current redistribution between excited quasiparticles and the superconducting condensate.
