Summary

The authors describe here the first observation of terahertz emission from unbiased YBa₂Cu₃O{sub 7−δ} (YBCO) thin films. These films are excited by 150 fs, 1.5 eV and 3.0 eV, optical pulses for a range of temperatures, T, 4 K < T < 300 K and for a range of oxygen doping from optimally-doped (δ = 0) to insulating (δ = 0.8). They demonstrate that this emission is generated by optical rectification due to the bulk electric quadrupole source term, comprising the first observation of such a source term in terahertz emission.
