Experimental comparison of broadband rotational coherent anti-Stokes Raman scattering (CARS) and broadband vibrational CARS in a flame

Broadband rotational coherent and anti-Stokes Raman scattering (CARS) and vibrational CARS measurements have been performed to determine the N(2) temperature in a flame (1800-2000 K). Comparisons between these two CARS approaches indicate that, despite loss of signal strength with increasing tempera...

Description
Summary:Broadband rotational coherent and anti-Stokes Raman scattering (CARS) and vibrational CARS measurements have been performed to determine the N(2) temperature in a flame (1800-2000 K). Comparisons between these two CARS approaches indicate that, despite loss of signal strength with increasing temperature, rotational CARS is a potentially viable technique for flame-temperature measurements.
