摘要：
Laser two-photon ionization spectroscopy is proposed as a selective and sensitive method of monitoring atmospheric pollutants in situ. The technique is demonstrated in the laboratory for a prototype molecule, aniline, in air at 1 atm. Advantages over existing laser-based methods are discussed, and an ultimate detection limit of <1 part in 1011 is estimated using currently available technology. © 1979, Optical Society of America.
