摘要
We observe terahertz radiation from Y0.7Pr0.3Ba2Cu3O7 (YPBCO) thin films excited with femtosecond optical pulses, and compare its waveform and efficiency with those from YBa2Cu3O7-delta (YBCO). It is found that YPBCO can produce much stronger radiation than YBCO. We discuss the origin of the enhancement as well as the temperature dependence of the emission properties.
