摘要: Light scattering from a laser-induced thermal grating produced in an atmospheric-pressure H(2)/O(2) flame is observed with phase-matching geometry commonly used resonant four-wave mixing and spectroscopy. The presence of gratings confirmed both the time frequency domains two distinct experiments. Diluting helium decreases signal intensity. Experimental results agree well calculations based on solution linearized hydrodynamic equations.
