Paper Abstract
Raman scattering techniques have long been used as unique identifiers for spectral fingerprints of chemical and
biological species. Raman lidar has been utilized on a routine basis to remotely measure several constituents in the
atmosphere. While Raman scattering is very reliable in uniquely identifying molecules, it suffers from very small
scattering cross sections that diminish its usefulness at increased ranges and decreased concentrations of the species of
interest. By utilizing a resonance Raman technique, where the laser excitation is tuned near an electronic absorption
band, it is possible to increase the Raman scattering cross section. An optical parametric oscillator (OPO) with a UV
tuning range of ~220 nm - 355 nm has been utilized to explore the wavelength dependence of Raman scattering for
diamond, water, benzene, and toluene. Resonance enhancements of the Raman spectra have been studied.
