Subpicosecond single-shot waveform measurement using temporal imaging

The recording of single-transient phenomena with a very large time-bandwidth product is a particularly challenging task. While many techniques have been developed to record ultrafast optical signals with sub 100 fs detail they often have practical limitations on the total amount of time that can be recorded or rely on sampling of a repetitive waveform. A waveform manipulation technique known as temporal imaging is being developed to overcome some of these limitations. Temporal imaging can expand an arbitrary optical waveform in time while maintaining the shape of the unknown envelope profile, thus allowing it to be recorded by a slower technology with a resolution improved by the magnification of the imaging system. We present here the first single-shot temporal images produced with an upconversion temporal imaging system and recorded with a streak camera
