Abstract: (1813 Views)
In this paper propagation of fiber laser beam with 1 wavelength was investigated in various atmospheric turbulence levels for 1km target range. It is found that intensity of laser beam decreases by increasing turbulence. During the propagation, other important beam parameters are also affected by atmospheric turbulence. Regarding laser applications in atmosphere, the coherent and incoherent beam combining methods are investigated. In various turbulence levels, by comparing peak intensity and spot size parameters on the target, it was observed that in many applications, we can use incoherent combining methods instead of coherent.
Keywords: Atmospheric turbulence, Incoherent beam combining.
