Pulsed laser heating of current biased percolative YBa2Cu3O7-delta-films can be used to generate and release self-field induced vortices. A laser pulse yields a voltage signal due to penetration of bias current induced magnetic flux in absence of an external magnetic field. Upon recooling, strongly pinned vortices remain in the film. These remanent vortices have been detected after disconnecting the bias source in the currentless film. Applying a subsequent second laser pulse, again yields a signal voltage but of inverse sign due to magnetic flux redistribution.
