Nonlinear spectroscopy of YBaCuO and Ni thin films by a biharmonic pumping technique
High temperature superconducting (HTSC) (YBaCuO, critical temperature T c=87 K) and metal (Ni) thin films are investigated by a picosecond spectrometer with two tunable dye lasers. The selfdiffraction process efficiency η versus the biharmonic pumping component detuning Ω has been measured at tem...
