-an order-of-magnitude improvement over state-of-the-art DCS, coupled with long-term stability. The system resolves weak molecular overtone spectra on nanosecond timescales, in a single-shot measurement, with absorption noise as low as 2%, markedly lower than prior demonstrations. This integration of high sensitivity and speed resolves the core trade-off that has long constrained time-resolved spectroscopic analysis.
