It provides a novel analytical demonstration that atmospheric turbulence decreases modulational instability growth, thereby reducing multiple filamentation during laser propagation.

Findings

Turbulence reduces the growth rate of modulational instability.

Decreased instability leads to fewer filamentations.

Analytical approaches confirm the stabilizing effect of turbulence.

Abstract

Multiple filamentation poses a significant challenge for laser pulse propagation in the atmosphere. This article investigates how atmospheric turbulence influences the development of modulational instability, which leads to multiple filamentations. Through various analytical approaches, we demonstrate that the growth rate of this instability decreases when the refractive index exhibits stochastic behavior.
