title: Direct measurement of OH local concentration in a flame from the fluorescence induced by a single laser pulse.
abstract: An alternative to the saturation approach is proposed to avoid the quenching dependence of the fluorescence intensity. The method allows direct absolute measurement of the local number density from a single laser shot. A mean quenching cross section of 5 x 10(-19) m(2) is deduced from the experiments, and a OH concentration profile through the flame is given.
