摘要：

This paper presents a study of OH detection by degenerate four-wave mixing (DFWM) in a premixed laminar CH4-air flame, at pressures varying from 1 to 7 bar. The P and Q branches of the A2-SIGMA+-X2-PI electronic transition are observed. A spectroscopic study is performed and saturation and pressure effects on the lineshapes and concentration profiles are presented. A preliminary comparison between CARS and DFWM is given.
