Nonlinear ultrafast dynamics of high temperature YBa sub(2)Cu sub(3)O sub(7- delta ) superconductors probed with THz pump/THz probe spectroscopy

High power THz pulses induce near transparency in superconductive YBCO thin films below the critical temperature. THz pump/THz probe measurements reveal a decay of the induced transparency on the time scale of a few picoseconds.
