Abstract:

The current progress in the technology of high-power femtosecond lasers opens new promises in solution of urgent problems of atmospheric optics. In particular, stable supercontinuum of directed white light generated in the atmosphere by a high-power laser pulse can be used as a white-light lidar for remote analysis of optical and microphysical properties of atmospheric aerosol. Using the experience gained in solving inverse problems of laser sensing, we develop the technique for solution of such problems with the use of a white-light lidar. As a first and necessary stage of the study, a closed numerical experiment was conducted. This paper discusses its results as applied to multifrequency sensing of aerosol along vertical paths in the visible and near-IR spectral ranges. Spectral ranges for sensing are selected, and noise immunity of the retrieval algorithms at wide-aperture reception is analyzed.
