Technique for single-shot time-resolved spectroscopy of irreversible chemical processes utilizing specialty dual-core optical fibers

Abstract

When photo-induced irreversible chemical transformations are repeatedly triggered by short laser pulses during time-resolved measurements, they can distort the observed dynamics. For instance, in studies involving microscopic biological samples, repeated exposure to intense optical pulses in pump-probe sequences may lead to sample degradation. To mitigate this issue, single-shot spectroscopy techniques employing sequences of short probe pulses have been developed to minimize sample damage and preserve measurement integrity.
