Abstract

Le dispositif pour étudier un milieu 3 gazeux ou liquide transparent par diffusion Raman anti-Stokes cohérente comprend deux sources continues de laser 1 et 2, la source 2 étant accordable en fréquence, des moyens optiques pour superposer les ondes émises par les deux sources de laser 1 et 2 et des moyens pour détecter l'onde anti-Stokes diffusée après interaction entre le milieu 3 à étudier et les ondes superposées précitées. La cavité du laser 1 formée par les éléments M1 , P1 , M2 et M3 est couplée avec la cavité du laser accordable 2 formée par les éléments M4 M5 , P2 , M6 , M7 , P1 , M2 et M3 et le milieu 3 à étudier est placé dans ces deux cavités couplées. Application à la spectroscopie Raman et à l'étude des fluctuations de la densité et de température dans les écoulements gazeux.
