Ultra-long duration time-resolved spectroscopy with enhanced temporal resolution of high-Q nano-optomechanical modes using interleaved asynchronous optical sampling (I-ASOPS)

Siddiqui, Aleem; Jarecki, Robert L.; Starbuck, Andrew L.; Cox, Jonathan A.

Transient responses of high-Q nano-optomechanical modes are characterized with Interleaved-ASOPS, where pump-induced transients are interrogated with multiple probe pulses. Temporal resolution increases linearly with probe-pulse-number beyond conventional ASOPS, achieving sub-ps resolution over μs durations.
