Abstract

The results of two-wavelength rotational CARS thermometry (2λ-CARS thermometry) of hydrogen at temperatures from 300 K to 1100 K are presented. Experimentally, temperature was measured in a heated cell using single-shot and averaged CARS intensities in the rotational S-branch. Relative standard deviation for single-shot temperature values was ∼1.5% at 296 K and ∼8% at 1000 K. The accuracy achieved, its dependence on measured temperature, and possibility of their improvement were analysed.
