Measuring complex pulses with time-bandwidth products exceeding 65,000 using multiple-delay crossed-beam spectral interferfometry

摘要

We measure the complete electric field of extremely complex ultrafast waveforms using the simple linear-optical, interferometric pulse-measurement technique, MUD TADPOLE. In its scanning variation, we measured waveforms with time-bandwidth products exceeding 65,000 with ~40 fs temporal resolution over a temporal range of ~3.5ns. In the single-shot variation we measured complex waveforms time-bandwidth products exceeding 65,000. The approach is general and could allow the measurement of arbitrary optical waveforms.
