Lidar Probing of Raman Scattering by Hydrofluoride Molecules in an Atmospheric Boundary Layer
Autor: Vadim E. Privalov, V. G. Shemanin
Publikováno v: Journal of Applied Spectroscopy. 88:802-806
The lidar equation for Raman scattering of light by hydrogen fluoride molecules is solved in order to select the laser wavelength and lidar parameters and to obtain a minimum time for measuring the Raman scattering signal corresponding to the minimum

Laser Gain for Inhomogeneous Boundary Conditions
Autor: Vadim Andreevich Kozhevnikov, Vadim E. Privalov
Publikováno v: Russian Physics Journal. 63:1631-1638
The method proposed by the authors for solving the Helmholtz equation with homogeneous boundary conditions was verified for an elliptic cross section. The method is generalized to the Helmholtz equation with inhomogeneous boundary conditions. The gen
