ation, Amplication, and Measurement of Ultrashort Laser Pulses II." Temporal imaging with the up-conversion time microscope

We have demonstrated a temporal imaging system with a novel time lens which magnies 100 Gb/s optical data by a factor of twelve. The function of a time lens is to impart a quadratic phase modulation or linear frequency sweep to the waveform under study. Our approach to achieving time lens action is to up-convert the waveform under study using a linearly swept pump, thus imparting a linear frequency sweep to the waveform. This technique allows for much greater frequency sweep rates and hence shorter focal times than can be obtained with electro-optic modulators. Additionally, the increased bandwidth that can be obtained optically instead of electro-optically should result in higher resolution in a temporal imaging system
