Abstract
A device for high-speed real-time sampling of mid-infrared ultrafast light signals includes a time domain amplification unit and a detection unit. The time domain amplification unit is used to perform sampling and time domain amplification on signal light incident to the time domain amplification unit, and convert the signal light of a mid-infrared band into a near-infrared/visible band. The detection unit is used to receive and record information of the to-be-detected signal light processed by the time domain amplification unit to realize high-speed real-time sampling and measurement of the mid-infrared ultrafast light signal. The present disclosure can accurately obtain subpicosecond transient characteristics of the light signal, breaks through the capacity limit to the response rate of a traditional photoelectric detector, the bandwidth of the oscilloscope and the like, and is applicable to femtosecond-level mid-infrared ultrafast light signals.
