Abstract EN
Distortion of laser-induced fluorescence profiles attributable to optical absorption and saturation broadening was corrected in combination with laser absorption spectroscopy in argon plasma flow.
At high probe-laser intensity, saturated absorption profiles were measured to correct probe-laser absorption.
At low laser intensity, nonsaturated absorption profiles were measured to correct fluorescence reabsorption.
Saturation broadening at the measurement point was corrected using a ratio of saturated to non-saturated broadening.
Observed LIF broadening and corresponding translational temperature without correction were, respectively, 2.20±0.05 GHz and 2510±100 K and corrected broadening and temperature were, respectively, 1.96±0.07 GHz and 1990±150 K.
Although this correction is applicable only at the center of symmetry, the deduced temperature agreed well with that obtained by LAS with Abel inversion.
