Abstract

In this article, we probe the atmosphere disturbance such as Attenuation, Scattering, turbulence and thermal blooming on the laser beam propagated it. For investigating, we designed software which gives the vertically propagation characteristics of a general-type beam in atmosphere, based on the Huygens–Fresnel principle. When the required source and medium parameters are entered, the simulator yields the average intensity profile along the propagation axis in a video format. The results show that the peak value of the average intensity can be astonishingly affected by atmospheric turbulence, thermal blooming effect (for typical high power lasers) and the laser beam diameter.
