L’étude expérimentale des processus physico-chimiques de la combustion nécessite de disposer de diagnostics non-intrusifs. Le présent manuscrit reporte le développement du diagnostic laser de mesure de température DRASC (Diffusion Raman anti-Stokes Cohérente) en régime d’impulsions laser femtoseconde pour lequel la configuration à sonde à dérive de fréquence (CPP) a permis d’effectuer des mesures instantanées de température à 1kHz. Un travail à la fois théorique, numérique et expérimental a permis d’extraire la température des spectres DRASC instantanés acquis dans des mélanges air/argon (300-600K) et en flamme prémélangée CH4/Air avec une précision de l’ordre de 1% à 2100 K. La validité de ces résultats est obtenues par des confrontations...
