The authors describe here the first observation of terahertz emission from unbiased YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} (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 ({delta} = 0) to insulating ({delta} = 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.
