Title: Terahertz emission from YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} thin films via bulk electric-quadrupole-magnetic-dipole optical rectification

Abstract

We report the observation of terahertz emission from YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} thin films excited by 1.5-eV, 150-fs pulses in the absence of external electric or magnetic fields. This emission is characterized for optimally doped {delta}=0 films and underdoped {delta}=0.5 films, over a range of temperatures T, 4 K<T<300 K, where the films change from superconductors to correlated metals. It exhibits a pronounced 4{phi} dependence with respect to the azimuthal angle {phi}. We demonstrate that this emission is generated by optical rectification due to the bulk electric quadrupole and magnetic dipole source terms. A model of this emission, assuming that the nonlinearity results from transport of carriers with different masses and relaxation times in the three crystallographic directions, is consistent with the data. A fit of the data to this model yields values for the anisotropic masses and relaxation times in YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} thin films. (c) 2000 The American Physical Society.
