… Here, we discuss new measurements made with a mid-infrared optical parametric
oscillator (OPO) during the combustion of hydrocarbons inside a shock tube. Multi-species
measurements of several hydrocarbons were obtained using a single laser at fast
timescales of combustion (µs to ms). … Speciation measurements for C2H6, and C3H6
were demonstrated during the pyrolysis of C3H8 using a broadband MIR OPO with an
instantaneous bandwidth of 2.80-3.57μm (3571~2801cm-1). Experiments were done over …

Simultaneous time-histories during the pyrolysis of propane were achieved behind a reflected shockwave using a mid-infrared frequency comb. Data was collected at temperatures ranging from 1105 – 1304 K and pressures of about 4 – 5 atm.
