Abstract

Results of numerical simulation of the return flux from a sodium laser guide star for atmospheric conditions of astronomical observatories of the North Caucasus are presented. The simulation is performed in accordance with modern concepts of the physics of the interaction of polarized laser radiation with mesospheric sodium atoms. Two cases of producing an artificial reference source by laser radiation, with circular and linear polarizations, are considered. The limitations of the photon flux due to the saturation effect are estimated.

模拟北高加索天文观测站偏振光产生的钠 LGS 返回通量

摘要--介绍了针对北高加索天文观测站大气条件的钠激光导星返回通量的数值模拟结果。模拟是根据偏振激光辐射与中间层钠原子相互作用的现代物理学概念进行的。考虑了用激光辐射产生圆偏振和线偏振人工参考源的两种情况。估算了饱和效应对光子通量的限制。

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.
