摘要: The technique of laser induced fluorescence saturation spectroscopy is evaluated for determination absolute atomic and molecular concentrations in flame sources. combustor an aspirating slot burner using premixed acetylene air to create a stable homogeneous source. Concentration measurements sodium MgO (X 1Σ+ A 1Π) are made by techniques. Independent absorption Na (X 1Σ+) which agreement with concentration determinations. effect various beam profiles (rectangular, Gaussian, truncated Gaussian) evaluated. It found that exists the significant inversion (A 1π) state possible production mechanisms considered.
