Paper Abstract

Picosecond voltage pulses were generated in YBCO microstriplines by irradiation with a picosecond laser. An autocorrelation method was proposed and applied to measure the temporal decay of these ultrafast voltage pulses. It was also ascertained that these pulses were generated in the superconducting state. Using a 40 ps laser, voltage pulses with fast components < 40 ps were obtained. This fast decay was dependent on the bias current. There were also significant thermal components in these pulses. Methods of generating even shorter pulses are discussed.
