摘要：In apparatus and methods of Raman spectroscopy in air, a target region isexcited by a laser pump pulse exceeding the critical power for self-focusing in air andhaving a duration after self-focusing of 15 fs or less. A laser probe pulse having a

duration in the range of 200 fs to 100 ps and an energy of at least 20 μJ is directed at theexcited target region. Stimulated Raman scattering from the interaction between theexcited target region and the laser probe pulse is detected. The target region can beoutside the spectrometer, with ambient air in between used for the self-focusing.
