A nonconventional technique for the measurement of magnetic relaxation in superconducting films at short times is described. This technique combines the application of a pulsed magnetic field and a synchronized high-energy pulsed laser. Remanent magnetic relaxation in thin films is reported over five decades time at reduced temperatures above 0.8.
