Ultrabroadband detection of a mid-IR continuum by chirped-pulse upconversion.
Ultrabroadband mid-IR continuum pulses can be detected on a single-shot basis using chirped-pulse upconversion. Converting the mid-IR pulse to the visible reduces the fractional bandwidth and enables use of a silicon CCD camera. Removing the cross-phase modulation of the chirped pulse results in 1 cm(-1) resolution over a 600 cm(-1) detected bandwidth.
