Abstract

Multiple filamentation poses a significant challenge for laser pulse propagation in the atmosphere. The purpose of this article is to explore how atmospheric turbulence influences the development of modulational instability, which results in multiple filamentation. We confirm a result that we previously published. We show through multiple analytical approaches that the growth rate of this instability decreases when the refractive index displays stochastic behavior.

在激光脉冲的传播过程中，由于大气湍流导致的多重灯丝的减少

多丝化对激光脉冲在大气中的传播提出了重大挑战。本文的目的是探讨大气湍流如何影响调制不稳定性的发展，从而导致多重灯丝。我们确认了之前发表的一个结果。我们通过多种分析方法表明，当折射率表现为随机行为时，这种不稳定性的增长率降低。

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
