Abstract
Current biased films of YBa2Cu3O7−δ (YBCO) are illuminated by short pulses of laser light and transient voltages are measured for a range of temperature 10 K <T < 250 K. Near the superconducting transition temperature Tc a bolometric response is observed. Below Tc signals are observed that cannot be explained by a bolometric mechanism. These signals, with decay times of the order of hundreds of picoseconds, are characterized and discussed.Keywords
