    Title: TRANSIENT RESPONSE OF SUPERCONDUCTING Pb MICROBRIDGES IRRADIATED BY PICOSECOND LASER PULSES AND ITS POTENTIAL APPLICATIONS
    Authors: CHI, CC;LOY, MMT;CRONEMEYER, DC;THEWALT, ML

    Date: 1981

    picoseconds
    Abstract: The authors observed voltage pulses having half-widths of less than 500 ps generated by constant-current-biased superconducting Pb variable thickness microbridges driven normal by short (3 EM DASH 5 ps) light pulses. This represents a step to generate even shorter pulses, which according to an analysis of the Rothwarf-Taylor equations should be possible. The ultimate width should be equal to the phonon pair-breaking time which, for materials such as Nb, can be a few picoseconds. In addition to monitoring the voltage pulses directly use was made of a novel adoption of the optical autocorrelation technique having a time resolution limited only by the laser pulse width. It is pointed out that even shorter voltage pulses, and therefore greater potential for device applications, can be achieved by direct injection of quasiparticles.
