    A fiber-optic multiphoton ionizatin detector was constructed. A pair of gold electrodes was fixed at the end of a fuxed-silica glass fiber of 1 mm diameter, and this end was dipped into a sample solution. Pulsed laser light at 355 nm was introduced into the fiber, and the current resulting from the two-photon ionization of an analyte was measured and analyzed. The detection limits for several polycyclic aromatic hydrocarbons were determined; the lowest was 0.12 ng ml-1 for anthracene and 9,10-dimethylanthracene. The laser power could be very low.
