title: Differential-absorption lidar measurements in the oxygen A band using a ruby lidar and stimulated Raman scattering.
abstract: Stimulated Raman scattering has been used to convert the output wavelength of a ruby-laser radar (lambda = 6943 A) into the oxygen A band near 7660 A. The system has been used to measure the energy backscattered from the lower atmosphere at both 6943 and 7658 A. Smith and Platt [NOAA Technical Memorandum, NESS 89 (1977)] have shown that such differential-absorption lidar measurements can be used to give both pressure height profiles and vertical temperature profiles. Some correlation between pressure height and oxygen absorption has been found, but greater transmitted energies and better frequency stability at the converted wavelength are required before an operational system can be implemented.
