摘要：
Experiments on the nonequilibrium resistive response of YBa2Cu3O7-x superconducting thin films to laser radiation are reported. Separate fast and slow components of the photoresponse were observed. Photoresponses to a sequence of laser pulses of various amplitudes were investigated. A memory effect has been observed, revealing a correlation between the photoresponse pulse amplitude and the preceding laser pulse amplitude. A theoretical model of the memory effect is suggested.
