The results of measurements of the temperature field in a hydrogen-oxygen flame by means of broadband coherent anti-Stokes Raman spectroscopy are presented. The measurements were performed at pressures up to 1.7 MPa and temperatures ~3000 K with the spatial resolution of ~0.04 × 0.04 × 2.5 mm3. The duration of a single measurement was 10 ns and the sampling rate was 10 Hz. The error of the temperature determination was ~4% for the single-shot measurements and ∼0.15% for the measurements of the average values during 100 s under quasi-stationary burning conditions.
