Thermometry of an oxy-acetylene flame using multiplex degenerate four-wave mixing of C-2

Abstract:

Thermometry of an oxy-acetylene flame using multiplex Degenerate Four-Wave Mixing (DFWM) of C2 is demonstrated. More than 100 rotational transitions in the d3Πg → α3Πu (0, 0) Swan band of C2 could be recorded simultaneously by use of a pulsed, broad bandwidth "modeless" laser. Temperatures were inferred by fitting temperature-dependent synthetic spectra of single- or multiple-shot averaged spectra. The strength and reliability of recorded signals together with the large number of rotational l...
