摘要
A system includes a first laser beam including a pulsed laser emanating from the instrument propagates in the air, wherein the first lase beam is tuned to the wavelength at which a target chemical absorbs, its pulses bringing molecules to an excited state, a second laser beam used to probe target chemicals by transient absorption spectroscopy, wherein the second laser beam is pulsed or continuous, and a detector.
