Dynamics of Al/Fe2O3 MIC Combustion from Short Single-Pulse Photothermal Initiation and Time-Resolved Spectroscopy

摘要

Time-resolved spectroscopy was used to study the dynamics of the photothermal ignition of Al/Fe2O3 metastable intermolecular composites after single short-pulse laser initiation. The dynamics were recorded in several time domains from nanosecond to microsecond to quantify the dynamics from initial laser excitation to combustion. Time-averaged spectral data were also collected for the overall emission occurring during combustion.
