Abstract

Transformation of spectral parameters of a femtosecond laser pulse propagating in the atmosphere and in pure molecular nitrogen in the filamentation mode is experimentally studied; its causes are analyzed. The spectral broadening of pumping radiation in a wide range, from 350 to 1100 nm, is shown to be due to the combined action of Stokes stimulated Raman scattering at rotational transitions of nitrogen molecules in air, coherent anti-Stokes scattering, and cascade parametric four-wave mixing. The study of these processes is to make it possible to create highly efficient white light sources for atmospheric spectroscopy and remote sensing.

期刊介绍： Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
