Delay-resolved intersubband spectroscopy
We present a delay-resolved spectroscopy method enabling accurate absolute gain measurements of terahertz QCLs, showing theoretical alignment below threshold at low temperatures, clamping post-lasing, and faster-than-expected gain degradation at higher temperatures.
