Propagation of a higher-order cosh-Gaussian beam in turbulent atmosphere

Analyzing the Propagation Behavior of a Gaussian Laser Beam through Seawater and Comparing with Atmosphere

Study of the beam propagation behavior through oceanic media is a challenging subject. In this paper, based on generalized Collins integral, the mean irradiance profile of Gaussian laser beam propagation through ocean is investigated. Power In Special Bucket (PIB) is calculated. Using analytical expressions and calculating seawater transmission, the effects of absorption and scattering on beam ...

Propagation of a Focused Laser Beam in a Turbulent Atmosphere

Propagation of Partially Coherent Beam in Turbulent Atmosphere: A Review

Partially coherent beam is preferred in many applications, such as free-space optical communications, remote sensing, active laser radar systems, etc., due to its resistance to the deleterious effects of atmospheric turbulence. In this paper, after presenting a historical overview on propagation of optical beams in turbulent atmosphere, we describe the basic theory for treating the propagation ...

Study on Turbulence Effects for Beam Propagation in Turbulent Atmosphere

Based on the theory for the turbulence and the Rytov method, the propagation formulas of the scintillation index and the mean square angle-of-arrival fluctuation for the beam propagation in atmospheric turbulence have been derived respectively. The propagation properties of the two turbulence effects have been investigated, and the effects of the characteristic parameters of turbulence and the ...

Gaussian Beam Propagation

Gaussian beams play such an important role in optical lasers as well as in longer wavelength systems that they have been extensively analyzed, starting with some of the classic treatments mentioned in Chapter 1. Almost every text on optical systems discusses Gaussian beam propagation in some detail, and several comprehensive review articles are available. However, for millimeter and submillimet...
