Two photon laser induced fluorescence of carbon atoms

摘要

Carbon atoms were generated by two photon absorption in carbon suboxide C3O2. Two photon laser induced fluorescence (LIF) excitation spectra using the 3thinsp;3DJprime;larr;2thinsp;3PJPrime;at 287 nm and 4thinsp;1P1larr;2thinsp;1D2at 284 nm transitions were intense showing that LIF is a convenient detection method for carbon atoms in their ground3Pand first excited1Dstates. Calculated values of the relative intensities of the seven allowedJprime;larr;JPrime; transitions were in good agreement with experimental values.
