Abstract

The transmission of laser beams in dense medium like cumulus will produce multiple scattering phenomena. The results of multiple scattering not only weaken the laser energy, but also lead to the broadening of laser pulse in time domain. In this paper, the scattering parameters of cumulus were calculated based on the Mie scattering theory and the Gamma size distribution model. The Monte Carlo simulation model was established, and the corresponding characteristics of the energy attenuation and the time domain broadening have been analyzed, for the transmission of the laser pulse with four different wavelengths in cumulus. The relationship of the transmittance with the thickness of cumulus and the time distribution curve of the transmitted light were obtained. The research results demonstrate significant application in laser communication and laser radar.
