The method based on the multiphoton Ionization Mass Spectroscopy/Supersonic Jet (MPI-MS/SSJ) technique for determination of trace concentration of toxic organic substances in the air is studied and applied in many laboratories in the world. A short pulse laser system with Fourier transform – limited bandwidth is suitable to the alternatively ionization process of the cold molecules. The Distributed Feedback Dye Laser (DFDL) pumped by a Nd:YAG picosecond laser is setup and employed to this purpose. The short laser pulse of 12 ps, which is exactly adjusted to wavelength of 316.14 nm and 315.83 nm with bandwidth of 0.05 nm, is corresponding to detect polychlorodibenzofuran and polychlorodibezodioxine.
