Abstract

It is demonstrated that the amplified stimulated emission technique can be applied for spatially resolved detection of flame species requiring a two-photon excitation process. The approach utilizes two laser beams of different wavelengths produced by a dual wavelength package in the dye laser. By wavelength separation through the use of two different doubling crystals fulfilling the phase-matching condition for only one beam at a time, followed by crossing the beams in the flame, a substantial increase in spatial resolution is achieved. The technique is demonstrated on ammonia in a jet and on carbon atoms in a welding torch flame.
